I got blankpage on my montage review page, the solution was to set timezone in options

[Tue Feb 02 10:30:55.613034 2021] [php7:error] [pid 595] [client 192.168.1.4:17590] PHP Fatal error:  Uncaught Exception: DateTimeZone::__construct(): Unknown or bad timezone () in /usr/share/zoneminder/www/skins/classic/views/js/montage

Default value is "use php.ini" but my php.ini have not set a timezone rather. I got the problem when i upgraded Ubuntu from 18.04.5 to 20.04.1, ZoneMinder (Dont know the old version, but at least back to 1.33.xx) and PHP from 7.2 to 7.4 in one go. I dont know where in that process the problem come, and its mayme my fault that do that much in one update.
But i think ZM can give a propper error message insted on blankpage
