 * I have a website bobs.org.au and have the following error message
 * Fatal error: Call to undefined function wp_suspend_cache_addition() in /home/
   brothers/public_html/wp-includes/cache.php on line 324
 * Warning: call_user_func_array() expects parameter 1 to be a valid callback, function‘
   wp_ob_end_flush_all’ not found or invalid function name in /home/brothers/public_html/
   wp-includes/plugin.php on line 429
 * I have not done any updates to the wordpress version or any plugins for about
   a week, and the site was working fine. I just noticed this error, and at a loss
   as to how it has happened. Any advise or suggestions as to how to get my website
   back would be appreciated.
 * Note : I do not have any auto updates on, so cannot work out why this has happened.

 * Try to deactivate all your plugins one by one until you find the one that is 
   causing the issue. If you don’t find it that way, switch your active theme back
   to Twenty Fourteen. If the issue is still present after that, your WordPress 
   installation is surely corrupt, and you’re gonna need to reinstall.
