I realize this thread is older, but I need help making this solution work. My server host must have security settings that are preventing the "attach files" button from working correctly and now that we're using XF 2 our members keep trying to use the attach files button even though it never completes the process, and I'm tired of repeating myself to those who can't/won't read my announcements that it is not functioning.
I tried the suggested template modification but I'm not very experienced with code at all and probably did not do it right as nothing changed. I'd like to make the button disappear so they'll look at the toolbar above and use the "insert image" button that actually works. I just need someone to please break down the addition of the code mentioned in more detail so my old, uninformed brain can figure out how to implement it. Thanks in advance.
