 * I have seen other people mention this, but cannot match the circumstances. I 
   am not a PHP programmer, but just noticed I am generating enormous error logs.
   
   All plug-in are up to date and am using BuddyBoss theme.
 * Full error is
    PHP Fatal error: Call to a member function wp_rewrite_rules() 
   on a non-object in /var/www/html/wp-includes/rewrite.php on line 510, referer:
   [https://explore.scimednet.org/wp-admin/post.php?post=7$](https://explore.scimednet.org/wp-admin/post.php?post=7$)
 * This looks like core code and is happening several times each minute.
 * Can anyone help please?
 * Thanks
 * Richard

 * disable all plugins and change your theme to twentysixteen. If the problem goes
   away, re-enable things one at a time until you see it return. Then, we have something
   to talk about.

 * Thank you. Will try this on my test server. I cannot do it on the live one.

 * Well that was interesting. When I looked at the error log on the test server,
   the error was not there. I then did a comparison of active plug-ins and discovered
   PhpSword Google Analytics was not installed. After installing it the errors appeared.
   I have now deactivated it on the live site and the errors have stopped as far
   as I can tell.
 * Thank you for pointing me in the right direction
