Hi there, i upgraded a site today from 2.2.1 to 2.3.1 no problem, then i added the event calendar and that seemed to go ok. i can add a calendar no problem, the problem i'm getting is when i add a calander event page it creates the page but everytime i try and save it the cms says "Error saving content". it may be there are some logs somewhere telling me more but apart from that i have no idea why it's happening. i added the dataobject manager as i read it helps but still no luck. Granted not much to go on here but maybe someone has had something similar, it's the latest version of the event calendar, download from the extensions page this morning.

Regards

Mick

Ok well thanks for trying if you do rememebr or if anyone else out there knows please let me know as this is a bit above my Silverstripe skill level.

Can you try removing all the tables from the DB, removing the event_calendar folder, run a /dev/build, and start over, maybe?
