    Hi, got these in my error log:

    
    [06-Nov-2018 15:13:17 UTC] PHP Fatal error:  Uncaught Error: Call to a member function cache_size() on null in /home/xxx/public_html/wp-content/plugins/cache-enabler/inc/cache_enabler.class.php:822

    seems to be happening on the admin dashboard.

  • Other (much lesser) log message:

    
    [06-Nov-2018 15:14:38 UTC] PHP Warning:  call_user_func() expects parameter 1 to be a valid callback, first array member is not a valid class name or object in /home/xxx/public_html/wp-content/plugins/cache-enabler/inc/cache_enabler.class.php on line 1293
    

    which seems to be related to the Permalink settings…

    Which version of Cache Enabler are you currently running?

    Hi, this is 1.3.1 on PHP 7.1 … and only when Permalinks are off, so disk cache is off too. Still the dashboard info tries to get cache size. The other call_user_func() create a warning too then.

    I’ve created a pull request on Github fixing the fatal error 🙂
