 * [@reuterpl](https://wordpress.org/support/users/reuterpl/): Hi,
 * A support thread would have been more appropriate for us to discuss looking into
   the issue together (and given me the chance to rectify the issue if was indeed
   caused by this plugin).
 * That said, how were you able to deduce that this plugin is at fault? The line
   of code referenced by the error message is for WordPress’s `get_user_option()`
   function which is not used directly or indirectly by the plugin.
 * Add the error is complaining that the function `get_userdata()` is undefined,
   but that’s defined in `wp-includes/pluggable.php` and should be available. Sounds
   like something else is going on.
 * Can you provide more details? Was it a specific page on your site causing the
   error? Have you tried switching to one of the default themes and deactivating
   all plugins and then activating *only* Add Admin JavaScript and testing things?(
   And then activate each other plugin in succession and test as you go).
 * Thanks.

 * Hi Scott,
 * I tested only one plugin “Admin JavaScript” and after installing it my WordPress
   crashed so I did not have access to admin page. I asked my hosting provider to
   recover back up from yesterday so eventually it fixed my problem.
 * Thanks for reply!
