Here is a strange problem I'm having with my gallery. When I try to download a video file I get a 500 error message. I went to the file on my server and changed the name and the download popup window came up. It doesn't work because the file name have been changed. The first time I erased the file from my server and this happened.
Why I'm having problems when the video file is there and when I remove it, it function correctly. I don't have any problems downloading pictures, just with videos or zip files.
