Errpr 400 / Call to a member function flush_rules() in PHP error log

  • Sometimes, seems randomly I encounter error 500 (internal server error) while browsing my website. In my PHP error log is see:
    [Tue Jul 26 14:27:01 2011] [error] [client 31.149.22.44] PHP Fatal error: Call to a member function flush_rules() on a non-object in /domains/domain.com/public_html/wp-includes/rewrite.php on line 93, referer: https://subdomain.domain.com/

    Any help is highly appreciated
    Thanks!

  • Have you tried:

    – deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

    – switching to the Twenty Eleven theme to rule out any theme-specific problems.
