 * Hello. At the top of my website recently it appeared error bug:
 * Warning: array_key_exists() expects parameter 2 to be array, null given in /nfsmnt/
   hosting1_1/0/0/00e9c28b-a183-4b5c-b1bb-007bba512ecb/nonstopfit.sk/web/wp-content/
   plugins/google-publisher/GooglePublisherPlugin.php on line 258
 * I installed any new plugins, or I’m not interfere with the operation of the page.
 * Someone had a similar problem? Thanks

 * Try deactivating all plugins. If that resolves the issue, reactivate each one
   individually until you find the cause.
 * If that does not resolve the issue, try switching to the Twenty Fifteen theme
   to rule-out a theme-specific issue (theme functions can interfere like plugins).

 * The problem is sometimes solved itself. And again it occurs. I can not get or
   disable modules, Anie switch between themes. Help

 * Try [manually resetting your plugins](https://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)(
   no Dashboard access required). If that resolves the issue, reactivate each one
   individually until you find the cause.
 * If that does not resolve the issue, access your server via [FTP or SFTP](https://codex.wordpress.org/FTP_Clients),
   navigate to `/wp-content/themes/` and rename the directory of your currently 
   active theme. This will force the default theme to activate and hopefully rule-
   out a theme-specific issue (theme functions can interfere like plugins).

 * This problem is more insidious. Sometimes appear, and then disappear again. Nobody
   met with the that? How i delete GooglePublisherPlugin ? Can be done ? I think
   it is built. Thanks

 * It’s not built-in.
 * Try manually resetting your plugins as directed in the guide linked to above.
 * Then, re-enter the Dashboard and simply delete the plugin from the Plugins section
   of the Dashboard.
