Error - PROBLEMS_STORING_EVENT_DETAIL

Hi,

I have a problem adding new events to the calendar. Problem has come since last Joomla/Jevents update.

First I got the message: <strong>403 You are not authorised to view this resource/perform this task</strong> and then I tried enabling Authorized access and added myself as authorized user but it didn't help.
Instead I got a new message: <strong>Error - PROBLEMS_STORING_EVENT_DETAIL</strong>

I checked the database in phpmyadmin and it seems the new events ARE created but does not get an ID number in the database file x_jevents_vevdetail - see the attached image.

I have tried to install Jevents again (without uninstalling) but it has not helped.

Any ideas how to fix this?

Thanks in advance for any help
