Recently I'm getting the following error that I think is related to the date format of a survey:
Fatal error: Call to a member function format() on boolean in /var/www/html/limesurvey/application/helpers/expressions/em_manager_helper.php on line 8704
I could reproduce it, but now I can't. Did you enter a specific date for the first date question (G1Q00005)? Or do you get the exception for all dates?
Yeah, the error appeared again. Maybe it's at specific time stamps... ><
Anyway, seems like the client is sending the server wrong date sometimes. I pick a date in July and get "2017-06-07 00:00" - which is today, but in the wrong format, so the server freaks out.
