Hi, all -- I've been using Xenforo for a few months now, and I'm still confused about permissions. Today I learned that some of my registered users are having trouble viewing attachments. When they click on them, they get an error message. Others don't seem to have any problem. So I figured it must be a permission problem. I have several user groups, so I went back and looked at all their permissions. ALL are set to view attachments. So that doesn't seem like it's the problem. I went back and looked at the individual users. Nothing unusual there, either. Is there something I've done wrong, or does anyone have a suggestion?
