 * After a recent update my login is blocked by a coding mismatch.
    Full message:
   Fatal error: Call to undefined function register_setting() in /websites/123reg/
   LinuxPackage21/ur/su/la/ursulaholdengill.com/public_html/wp-content/plugins/event-
   list/includes/options.php on line 70
 * I am happy to go to ftp and search for line 70 and adapt the ‘events list’ plugin.
   But I am not sure what to delete and what to replace it with.
 * Help would be amazing.

 * UPDATE: Realised I have switched the website to 123reg hosting and now I am unsure
   how to access backroom via ftp. (Previously hosted via a friend and I had all
   ftp login details).
