chrishajer, I use the following plugins:
BBcode Buttons Toolbar
Mass Delete Users
These are vital for me though, I got many users depending on these as core functions already. This problem did interestingly enough, occur after I had installed Mass Delete Users. Not imediatly though.
Deleting users works, but maybe it does something else that I can not see – that fucks up something else?
Do human test work for 1.02?
