After upgrading to version 2.4.2 I have had problems installing or using any of the calendar plug-ins. Are there any workarounds or new options available?
migxCalendars is based on MIGXdb. It is working on 2.4.x , too.
If you don't need that frontend-editing-stuff, the setup should be a bit easier.
There isn't an officially release, mainly because of missing documentation.
But you can ask me, if you need any help.
