Cannot fill in App ID and Secret

The Facebook plugin for WordPress verifies your entered App ID and App Secret values by exchanging for an app access token on save. If the values disappear it is likely your server could not communicate with Facebook servers. Some sites have reported issues with their server’s installed SSL certificates causing failed communication.

Thank you for your reaction, should I consider contacting my webhost? Is there a setting in the php.ini file that needs to be configurated?

You can view your server info at the bottom of the Facebook plugin for WordPress debugger settings page, typically located at wp-admin/admin.php?page=facebook-debug.

You should see text such as cURL 7.x.x; OpenSSL 1.x.x.

The Facebook plugin for WordPress uses the WordPress HTTP API to communicate with Facebook servers. cURL with SSL seems to work well for many WordPress sites.

WordPress 3.7 may include the Mozilla certificate bundle, which is the same fallback used by the Facebook SDK for PHP when it encounters cURL HTTPS errors.

I am having the same problem as above but I am not computer savvy like mcjefix. Are you able to translate the above answer into layman’s terms?

Your server needs to talk to Facebook’s servers over a secure line. WordPress abstracts the creation of connections between two servers into its own API which then interfaces with the best available option on your server. WordPress also has some limited support for letting plugins know the server does not support a secure way of communicating with a remote server.

Some servers and configurations test for the validity of a secure communication method by comparing against a known set of companies that issue secret makers understandable by your server. Your server may keep a separate, more limited list than modern software used to accomplish the same task.

Updating server software to support the most robust and well-supported way for WordPress to communicate with a remote server is good. Updating or upgrading a server for modern SSL certificates and communication is also good.
