We've updated our Typo3 installation to the 9LTS version and our Calendar Base to 2.0.1. Our list view works fine as well as our day view and the event view. But wherever the month view is included we get an PHP error message.
DateTime::__construct(): Failed to parse time string (Ymd000000) at position 0 (Y): The timezone could not be found in the database in XXXX\typo3conf\ext\cal\Classes\View\BaseView.php line 2135
I've read that this cal version works for some users. Does anyone have the same problem? Has anyone already got a solution to it?
