@PitaJ Got it, thanks a lot for your suggestions. I will try the installation process once again today.
0.11.x plugin statuses
I'm looking to upgrade from 0.10.x to 0.11.x. Is there a script or something which will tell me what plugins are not designed for 0.11.x?
Most likely there weren't any major breaking changes for plugins between those two versions. You should be okay to upgrade, although I'd back up your database just to be safe.
