 * Hi, I’m getting the following error on my single.php where the Facebook Comments
   are displayed: ‘Undefined variable: commenttitle in ‘theme-name/wp-content/plugins/
   facebook-comments-plugin/class-frontend.php on line 88’. Any ideas?
 * I should note that I’m on a local environment, and also see this in the console:‘
   Given URL is not allowed by the Application configuration: One or more of the
   given URLs is not allowed by the App’s settings. It must match the Website URL
   or Canvas URL, or the domain must be a subdomain of one of the App’s domains.’.
   Could that have something to do with it?

 * Last December I’ve asked the plugin author if he has a GitHub repository where
   we can send pull requests for things like that.
 * I’ll be more than happy to help fixing those issues if we have a place where 
   we can submit patches and issues 🙂
