did you changed anything else?
Because now forum is an empty blank page
also a new error is logged
file: /simple-press/forum/database/sp-db-statistics.php
line: 312
function: __construct
Warning | DateTimeZone::__construct() [datetimezone.–construct]: Unknown or bad timezone (UTC 1)
what is that timezone error that is often displayed?
N.B : i didn’t changed anything since my last post here.
