Crash: LoadError: cannot load such file -- bundler_ext

Ok, @ekohl & @evgeni, I’m now back to where I was before I started playing with foreman_column_view.

If I now want to try that plugin, how should I go about installing it? rpm?

That would be my advised approach. If it’s a VM, it might be good to make a snapshot before attempting so.

I did make a snapshot after getting it running again.
Now I even have the column_view plugin working as well.
Thanks for your help!
