    Hi,
    I like your plugin and it was working well.
    But now I get an error 500 when I am logging in to admin panel. If I disable plugin, everything seems to be working ok.
    If I re-enable, 500 error again appears.

    The most interesting, that this error is under admin, which has @ in login name. Other users (without special symbols) are working perfectly and don’t get any 500 error.

    Error log is as following (on this 500 error)
    [Wed May 24 19:00:55.799441 2017] [:error] [pid 30880] [client IP] PHP Fatal error: Call to a member function get() on null in /home/site.com/htdocs/wp-includes/query.php on line 28
    [Wed May 24 19:00:55.799619 2017] [:error] [pid 30880] [client IP] PHP Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0

    I have created user with Administrator rights without any special characters in user name. But problem exists for this user too, after login – error 500.
    The same error in error.log

    Hi, when did you notice the changes in your site? The reason why I am asking is because you say it was working well. Did you update or install new plugins? Did your host upgrade or made any changes to your server?

    Problem solved by:
    1) Remove plugin
    2) Remove w3 total cache
    3) Install, enable plugin with forceOff file
    4) Add my ip to white list
    5) Enable w3 total cache
    6) Clean all caches in w3 total cache
    7) Enable plugin and delete forceOff
