A quick bug fix resulting in you being able to create events again.
Only new installs seem to be affected. Cause, a wrong database field. This has been removed and code cleaned up in order to fix the problem.

The update is recommended for all users of Events.

[Update:]
For those who cannot add events or miss options in the dashboard, try re-saving the general settings to re-apply then access roles. This should solve most issues.
