Hank, thanks a lot for your answer! Actually, I'm still in development mode on the server - didn't even dare touching this yet. I'm really startled by the fact that the test complains about a "test" column. There is none, I just double-checked the database and the migrations. There is a "content_type" column because it's needed by attachment_fu, but I suppose this shouldn't be a problem. After all, I still really don't understand why it works on my laptop but not on the server using exactly the same versions of Rails and attachment_fu.
The error about the "test" column occurs when running "rake test" in the attachment_fu directory. Are there any other places that could have database definition? I noticed that "rake test" doesn't print any errors when run in the attachment_fu directory on my laptop.
