# Error When Saving Post "_disable_fbc"

 * [10 years, 4 months ago](https://wordpress.org/support/topic/error-when-saving-post-_disable_fbc/)
 * Using the latest version of the plugin and WordPress.
 * On my development environment with errors enabled, when this plugin is enabled
   if I try to save a page/post in for example a custom post type it shows a white
   page with the following error:
 *     ```
       Notice: Undefined index: _disable_fbc in /srv/www/example.dev/current/web/app/plugins/facebook-comments-plugin/class-admin.php on line 483
   
       Warning: Cannot modify header information - headers already sent by (output started at /srv/www/example.dev/current/web/app/plugins/facebook-comments-plugin/class-admin.php:483) in /srv/www/example.dev/current/web/wp/wp-admin/post.php on line 197

       ```
   
 * The only way to resolve it is to check “disabled comments” on that particular
   page/post. Does anyone know a permanent fix for this bug? Thanks!

 * I’m having this problem too! 🙁
 * I recently installed 2 plugins (tablepress + Yop Poll) could these be conflicting?
   I’ll get around to deactivating these and checking it out.

 * The plugin ended up crashing my whole site and I had to manually remove the plugin
   from my server. Can someone pleaseee help, I really need this plugin, what CSS
   should I add/change so that it will stop displaying error messages like OP?

 * **I fixed the problem for me.**
 * The Facebook comments plugin was clashing with another plugin that was active
   on the post. It was clashing with ‘Yop Poll’, when I deactivated and deleted 
   the plugin I haven’t had an issue yet.
 * So for those with this problem I’d say it’s most likely a plugin clash. Hope 
   this helps.

 * Also if your site crashed so bad that you can’t even open it anymore you are 
   going to have to manually remove the Facebook Comments plugin from your server,
   I had to resort to this.
