Hi @caimin_nwl,
I have the same problem as the others. I see a few topics concerning the same problem, but no real solution. When I activate Events Manager I get an 500 error and the admin panel is unreachable.
I have tried it with all other plugins deactivated and with the standard theme, but no luck. Maybe this error log helps somehow:
