Facebook Comments for WordPress not working?

Just a quick post here on a great little plug-in for WordPress – Facebook Comments for WordPress

After looking through a sea of plug-ins we finally settled on this great one (props for the intro and testing it go to Jay Thompson, the Phoenix Real Estate Guy).  It does everything most will need and doesn’t have the Wall Spam issues of so many others.  But we’ve found that many are having an issue where it simply doesn’t work!  The area where the plug-in should pop-up is there, but the comments section is nowhere to be found.

Here’s how to fix it, from easiest solution to biggest pains in the neck:   =)
Note that this assumes you’re running the most recent version and have gone through the setup properly.

a)  Under Settings / Facebook Comments – Scroll all the way to the bottom to the Advanced Settings options and check the second option [ Include Facebook JavaScript SDK (This should be checked unless you’ve manually included the SDK elsewhere) ] – We’ve found this fixes the problem for the vast majority of users.

a-2)  I didn’t have this listed before, but I guess it’s an important step.  🙂
MAKE SURE THAT THE FIRST BOX UNDER BASIC SETTINGS IS CHECKED!  Yes.  If you don’t check the box that says “ (Uncheck this if you want to hide the Facebook comments without having to deactivate the plugin), they will, in fact, not show up.

a-3)  Another new factoid provided today by Bev M Jamieson:  If WordPress comments are disabled, this plug-in will not work.  To use Facebook comments IN PLACE OF WordPress comments, enable both and get them working.  Then select the option to hide WordPress comments from within Settings / Facebook Comments / Basic Settings.  Thank you Bev for the addition.

b)  If you’re using Simple Facebook Connect (SFC) – You’ll need to deactivate it.

c)  Try to deactivate anything else that might communicate with Facebook.  Please note that Share-a-holic’s plug-ins do NOT cause any conflicts, so you don’t need to deactivate it.

d)  You may also want to enable the option in Facebook Comments for WordPress that hides WordPress comments where Facebook commenting is enabled.  It’s rare, but possible that your template’s CSS is a little messed up causing WordPress comments to be displayed on top of your Facebook comments.  If this ends up being the case, either contact your theme / framework developer for assistance or the company that designed your site for you.

Hopefully option A solves it for you though.  =)


Oh – and if you like what you read here – feel free to subscribe to our blog, and you’ll get new and nifty posts in your email.  We don’t spam.


Having issues with notifications not working? Once the plug-in is working, enable notifications so you know when someone has commented.

UPDATE:  Tim Wohlberg pointed out in the comments below that Sharedaddy’s Facebook ‘share’ button was also causing problems with this plugin.  (Thank you Tim!)  Please note that Sharedaddy is been integrated with WordPress 3.2.  It’s deactivated by default, but it’s in there, so be careful using it in combination with Facebook Comments for WordPress.

    Hi Jon,
    You seem to be a Facebook genius – I’m fiddling around with this great plugin but am experiencing some major issues. Can you help me out?

    First of all I can’t even get the comment box to show. I’ve tried adding the hook recommended, but that did not help, so I have removed it again.

    But mostly I believe the problem is this: Even though I set the App ID and Secret Code (correctly and it has worked with several other plugins) the system says: ERROR! Invalid application ID. Please double check to make sure it is correct. Note that this is not the same thing as your Facebook user ID

    I’m on WordPress 3.3 using Structure Theme.

    Cheers and your help is much appreciated,

      Hi Maria and thanx for the kind words. 🙂
      The short answer is yeah… It basically doesn’t work anymore. The plug-in seems to have been abandoned by its authors as keeping up with facebook’s changes has proven near impossible. Other FB based plugs including but not limited to facebook page publish have all seen similar problems and chosen to give up.

      But it sounds like you’re at the beginning of you integration which is a great thing for you. I’d dump this plug-in and consider something more stable like the Facebook plug-in, which was written by Facebook, Automattic and a few other well knows. You can get it here: http://wordpress.org/extend/plugins/facebook/

      You could also try looking at Automattic’s JetPack Commenting System that comes with JetPack, which you can get here: http://wordpress.org/extend/plugins/jetpack/

      The JetPack solution isn’t as social as I’d like, but it’s great because folks can comment using their FB or Twitter accounts.

      I know it’s probably not the answer you’re looking for, but trust me. We’ll be making the change soon too, and will loose years of comments as a result. 🙁

      Good luck to you!

    I am kinda with debbie on this. I love the FB plugin app. I think its a great idea. But I too fear adding extra pluggins for fear of crashing. Have you noticed the plugin slowing down the load time at all? Thanks for your help!

      Well… To be honest, I haven’t. We have seen FB comments not load when Facebook was having issues, so there is certainly potential for that becoming an issue, but we haven’t had a problem with yet. Another thing to note is that the Facebook Comments for Windows loads comments via iFrame, so it can’t really impact actual site load times. So if ranking issues as a result of load times is your concern, you won’t get penalized for performance issues within the iFrame. Having said that, folks don’t tend to visit you for the comments. If it’s not loaded by the time your visitors are done reading your posts, just write longer posts. LOL! (jk) Thanx for your comment!

      🙂 Glad you got it working. This, combined with FB post publishing really pushes traffic. Keep playing with it. 🙂

    I’m getting the same Fatal error 🙁

    Fatal error: Cannot redeclare class FacebookApiException in /path/plugins/facebook-comments-for-wordpress/scripts/facebook.php on line 91

    Please Tell me what to do? I’m using WordPress 3.2.1 with Facebook Comments for WordPress 3.1.3

    But not working..

      Sounds like a conflict of some kind. You’re going to have to do the ‘disable all plug-ins (less FB comments for WP) and see if it works’ trick. If it does, re-enable plug-ins one at a time until you figure out what’s causing it. It stinks, but it must be done.

    Hi Jon, make changes and do not solve the problem, not might happen, thank you for your attention

      Okay, if all those things still don’t bring back your original comments, you’re going to have to try to contact Facebook. The plug-in doesn’t store comments. That’s all facebook. While there are settings that can cause comments to ‘vanish’, we’ve confirmed that those are all set up properly. The only other issue there could be is if you deleted and created a new Facebook app. Then your old comments would be gone, but if this is the original app and you haven’t changed anything, Facebook themselves are the only one that would possibility have the ability to resolve the problem. You are not the first one to mention this recently. While we haven’t had the problem, there are several that have, and I’m still not sure what changed to cause this. I’m sorry I couldn’t be more help. 🙁

        Dear Jon, thank you for your time and help, I have supported but not resolved the problem for me is the most important since you took the attention and time. Thanks for everything and if I can solve this problem the solution certainly need to share with you. good day

          You’re very welcome. I look forward to hearing what caused all this. We’ll still be looking into it, but being that it’s not our plug-in, and Facebook is really hard to get a hold of, there’s just a limited number of things we can do. Thanx for the Facebook add by the way. 🙂
          Please do come back and let us know what happened. Best, Jon-

    Hi Jon, excuse my English:), I thank you in advance and hopefully can help me. I recently had problems with my wp installation and had to reload all over again in my api I can see the comments, but I can not show up or see them in the posts, I’ve tried everything and I can not fix it, you’ll have some idea how to fix it? New comments if there are no problems. It should be noted that started using the plugin v.2 from the beginning, so the problem with v.1’m not experiencing conflict is only with the v2. Thanks friend

      Hey there. I just left a test comment on http://www.ganandoeninternet.com/roberto-perez-opina-del-multinivel-por-internet. Please let me know if you can see it. Also, can you send me a link to an article that previously had facebook comments that isn’t displaying them now? We’ll see what we can figure out.

      I have noticed that there has been an increase in the number of people reporting problems since the recent facebook changes, and I’m starting to think all this might be related to those changes, but we will see if this can be resolved.

        Thanks Jon for taking the time to help me, this post was much comment with facebook http://www.ganandoeninternet.com/como-hacer-una-pagina-web-optimizada-para-tu-marketing but also the post where you let me comment on my app I see all the comments without problems, the problem is not published, in the case of the test message I just left if I can see and if published. Thanks friend

          Okay, now just for verification: You are using Facebook Comments for WordPress (latest version) and it was always set for v2? Are you positive? Have you tried it with ‘new’ instead of v2?

          The system seems to be working, less the fact that you can’t see any previous posts. So long as you haven’t setup a new Facebook App all the posts should be there, so this really looks like a version problem. Try new and see if your posts pop-up. If they do not, try version 1. If they still don’t show, this is also going to be a problem with the recent changes to Facebook.

          Unfortunately, I still don’t know what exactly they changed or what’s causing the problem, but I will be working on a new implementation of the plug-in this week, so I’ll see what I get figure out then.

          Please let me know how it goes.

      You’re too kind. 😉 Just glad you got it all working. Enjoy it, especially now that notifications are actually starting to work. Guess Facebook is finally getting around to fixing a few things. (with a little push from Google+)

    For me this plugin do funtcion. Only the counting of comments dosn´t start. You have any solution?

    • Inna Hardison
      June 3, 2011 | 7:10 pm

      Heming – the FB comments are not counted, at least not that we can figure out. That’s part of the reason we have both, FB comments and WordPress comments. Well that, and not really getting the notices when someone uses FB comments.

      • Heming
        June 3, 2011 | 7:43 pm

        Okay so that´s how it is, when you have both you get the wordpress comments counted so thats why i have seen numbers on some pages. Thank you very much, good to know its not me that dosnt find the solution!

    Thanks to your article, I’ve finally managed to make the FB comment system to work on my site! Great job here.

    For me it was option C. For the information of those who are hard up looking up conflicts and such, I deactivated the Digg Digg plugin and then everything worked out great! =)

    Thanks again!

      Perfect! Glad we could help. 😉 One thing to note, and this is working out to be a big issue: eMail notifications do not work. If you scroll through the FB comments above, you’ll notice we’re not doing a very good job of getting back to folks. This may be a reason not to use it.
      In the plug-in’s defense, It’s not their fault. It’s a Facebook problem, but as soon as a solution is found, we’ll be sure to post it. If anyone has got it working, please let us know. 🙂

    Still contemplating doing this! I crashed my site last week (clicking the stupid UPDATE button!) and am a bit plug-in shy right now!! 😉

    • Jon Hardison
      April 15, 2011 | 11:45 am

      Oh Debe, I’m so sorry. It happens to the best of us. 🙂 There are some things about it I find annoying, like NOT getting emails, and the fact that conversations can’t really be well managed between FB and your site. You’ve got to keep an eye out in more than one place which, for busier bloggers, such as yourself, might result in you getting a little lost, but for us… The benefits out-way the cost. 🙂
