Facebook Comments Vanished

Hey there!

Something happened and the facebook comments on all our posts disappeared. I did not make any changes that I know would cause this.

Please help.

Hey @ynrcon,

Please tell us the recent changes you’ve made to your site before this happened. And, also check or do for the following:

1. Ensure everything is up to date according to our version compatibility list at https://theme.co/apex/forum/t/troubleshooting-version-compatibility/195. Please follow the best practices when updating your theme and plugins. See https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62 for more details.

2. Clear all caches including browser cache then deactivate your caching plugins and other optimization plugins.

3. If you’re using a CDN, please clear the CDN’s cache and disable optimization services.

4. Test for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.

5. Remove custom CSS, Javascript and templates.

6. Contact your host to increase your allocated memory or do it yourself by adding this code in your wp-config.php

define( 'WP_MEMORY_LIMIT', '256M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );

Also note that we may deactivate plugins and remove customizations while we are troubleshooting. If those could not be done in your site, please copy your site to a staging server and we’ll investigate there.

Thanks.

The only thing I changed is adding the FB tracking pixel via functions.php

This is the code that I added:

//FB Pixel in header
function third_party_tracking_code_header() { ?>

<script>
!function(f,b,e,v,n,t,s){if(f.fbq)return;n=f.fbq=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};if(!f._fbq)f._fbq=n;
n.push=n;n.loaded=!0;n.version='2.0';n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];s.parentNode.insertBefore(t,s)}(window,
document,'script','https://connect.facebook.net/en_US/fbevents.js');
fbq('init', '506622302781068'); // Insert your pixel ID here.
fbq('track', 'PageView');
</script>
<noscript><img height="1" width="1" style="display:none"
src="https://www.facebook.com/tr?id=506622302781068&ev=PageView&noscript=1"
/></noscript>
<script>

<?php }
add_action( 'wp_head', 'third_party_tracking_code_header' );

After I remove the code, everything works fine…

<?php }
