It does not seem to be affecting the way my website is running but I have noticed the following in the error log.
[Thu Sep 10 13:32:11 2015] [warn] [client ********] mod_fcgid: stderr: PHP Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Berlin' for 'CEST/2.0/DST' instead in /var/www/vhosts/*******/wob/inc/classes/BxDolCalendar.php on line 121
it prints out on the error log every 5 minutes. Anyone else getting something like this in the error log?
