# Plugin update 5.12.5

 * Plugin update 5.12.5 crashes my WordPress site. I tested it and am now certain
   that it is the plugin that causes the problem. If I update to the new version,
   I get a fatal error that corrupts code on the page wp-includes/wp-db.php. I reinstalled
   a backup version of the site to restore it, but when I tried again to reinstall
   the plugin update, it crashed again. If I leave the plugin at version 5.11.5,
   it works correctly.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fplugin-update-5-12-5%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hello,
 * I can confirm that it is definitely an issue with MEC as my website is also suffering
   from the same issues. I have debugged and put it down to MEC and this function
   in wordpress ob_end_flush()
 * If i uninstall MEC then all my problems go away, my site suffers 500 errors on
   any page MEC is used.

 * Hi [@jiberson](https://wordpress.org/support/users/jiberson/),
 * Please make sure using the correct configuration for your server (especially 
   PHP):

 * Regarding the “ob_end_flush() function error”, please send a screenshot form 
   the error, so we will be forwarded this topic to the developer team and it will
   be fixed for the next updates.

 * I have no issues with my PHP configuration. I also have no issue if I disable
   MEC, but on enabling every page I try to access the uses it comes back with this
   error.
    Fatal error: Allowed memory size of 268435456 bytes exhausted (tried 
   to allocate 172032 bytes) in /var/www/vhosts/clubalfa.co.uk/httpdocs/wp-includes/
   functions.php on line 4669
 * This points to “ob_end_flush()” in these files.

 * I agree with jiberson, and I get the exact same fatal error. Also, I would not
   label my comment “resolved”, but rather responded to.
