Here is a list with many available languages in Facebook Facebook Language Codes
= What the message " Warning: http://somelink is unreachable. " Means? It mean's that Facebook can't find the page you're trying to use the SEO Facebook Comment. The reasons that could possibly lead to this are: * You haven't correctly configured the APP ID or APP SECRET * Facebook can't find the Host/Link of your page (this might happen if you are using a LOCAL HOSTED SERVER for example) * You didn't correctly configured all the necessary options in the http://facebook.com/developers page
Yes, in order to avoid excessive memory and server usage this plugins only updates the pages comments after someone loads that specific page.
So if someone update the page with a comment right now and someone else opens that page the comment will not appear to that user yet. It will, however, appear normally on the Facebook comments box.
Loading a page only make the Plugin sees that there is a new comment and that it should be added to the database, so in the next reload (2nd one) the comment will already appears at the page, if auto-approved or goes to the line of approval from the Admin.
The plugin uses a table that it creates (normally wp_comments_fbseo, depending on the prefix you used for your wordpress database tables) to keep track of all the added comments and also the facebook users that added that comment.
Be careful when managing those databases, if something goes wrong it can result in many duplicate comments.
On uninstall this plugin won't remove that table from database in order to avoid duplicating all the comments on a future re-install.
However you can access your database and manually remove the wp_comments_fbseo table, but keep in mind that it can cause you a lot of problems if you Reinstall this plugin later since it will duplicate all the Facebook Comments already added to your WordPress Database comments table.
= How do I insert the comments in my custom template or if I don't use the comment_template() wordpress default function?
Just add the action 'seo_facebook_comments' with the do_action() function wherever you want the comments to show. Example:
There are many options available through the admin page. But you can also change the file fbseo-style.css for custom layout. Keep a backup of the changes since it will be overwritten in future plugin releases.
