 * I recently migrated my website and everything is good to go except I have an 
   error message across the top of the page:
 * Warning: call_user_func_array() expects parameter 1 to be a valid callback, function”
   not found or invalid function name in /home/mymicl5/public_html/wp-includes/plugin.
   php on line 214
 * Line 214 of plugin.php states:
 * $value = call_user_func_array($the_[‘function’], array_slice($args, 1, (int) 
   $the_[‘accepted_args’]));
 * This is apparently a plugin API ( whatever that means). I know nothing about 
   plugins. Can someone tell me how to fix this?

 * 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).

 * Ok, I tried both of the options you suggested and neither worked. Any thing else
   you can suggest? 🙂

 * Try [downloading WordPress](https://wordpress.org/download/) again and delete
   then replace your copies of everything **except** the `wp-config.php` file and
   the `/wp-content/` directory with fresh copies from the download. This will effectively
   replace all of your core files without damaging your content and settings. Some
   uploaders tend to be unreliable when overwriting files, so don’t forget to delete
   the original files before replacing them.
