 * I currently have debugging turned on on my site and I keep getting the following
   error:
 * > Notice: has_cap was called with an argument that is deprecated since version
   > 2.0.0! Usage of user levels by plugins and themes is deprecated. Use roles 
   > and capabilities instead. in \wp-includes\functions.php on line 4020
 * Which I’m sure if I turn off errors would be fine. It appears at the top of the
   admin site on every page then again in the Settings menu above the plugin page“
   Facebook Members”.
 * On the “Facebook Members” page there’s additional errors:
 *     ```
       Notice: Undefined index: as_facebook_mem_stream in \plugins\facebook-members\facebook-members.php on line 148
       Notice: Undefined index: as_facebook_mem_header in \plugins\facebook-members\facebook-members.php on line 149
       Notice: Undefined index: as_facebook_mem_faces in \plugins\facebook-members\facebook-members.php on line 150

       ```

 * This is a debugging error caused by turning the DEBUG option to True. You can
   check the article on [has_cap error](http://computertips.exploremyindia.in/2017/03/has_cap-was-called-with-an-argument-that-is-deprecated.html)
   for a possible resolution of your problem.

 * [@rspandey62](https://wordpress.org/support/users/rspandey62/) Thanks for the
   reply but the cause isn’t DEBUG the cause is the plugin, debug is just reporting
   the cause of the issue. Unfortunately, I cannot resolve the issue myself without
   modifying the plugin directly, which would be overwritten whenever the plugin
   updates and is highly unadvisable.
 * It’s the theme author’s responsibility to resolve these kinds of issues.
