When I’m trying to activate the Multi-event-registration-plugin for EE4 the following error occurs and the plugin gets deactivated again:
An error has occurred:
The Event Espresso “Multi_Event_Registration” addon was deactivated because it is incompatible with this version of core.
Only version 2.0.11.rc.002 or higher of “Multi_Event_Registration” can run with this version of core. This can happen when attempting to run beta versions or release candidates with older versions of core, or running old versions of addons with a newer version of core.
Please upgrade Event Espresso Core and the “Multi_Event_Registration” addon, then re-attempt activating it.
Any clue what I could do? I already tried updating but cannot see any…
Thx for your help!
Cheers
Philip
Most likely the easiest way to update MER on your site at this point will be to delete the plugin, and download a fresh copy of Multi Event Registration from your account page. Then you install using the zip uploader on your WordPress > Plugins > Add new page.
I tried already… but now tried again and it worked the 2nd time – I guess there was something else that didn’t work…
Cheers
