 * Help! My site is down with a fatal error –
 * Fatal error: Class WP_Hook contains 1 abstract method and must therefore be declared
   abstract or implement the remaining methods (ArrayAccess::offsetUnset) in /home5/
   altituh3/public_html/funkykat/wp-includes/class-wp-hook.php on line 510
 * I’ve tried deleting/disabling plugins, changing back to default theme, replacing
   class-wp-hook.php file but nothing worked. I’d just updated to the latest version
   of WordPress and enabled SSL when it threw this error 😢
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ffatal-error-class-wp-hook%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * WP_Hook doesn’t contain any abstract methods.
 * Make sure you have the correct files. Download a fresh copy of WordPress, and
   replace your files with the original ones.

 * Okay I did that, and still getting the same error :o[
 * I still dont fully understand the error terminology- the purpose of wp_hook and
   its abstract methods!
