Yes Jelle, I thought of that as well and worked it out. The problem was being caused by vBSEO - DownloadsII. It's an add-on for your own mod, re-writing all the downloads to SEF urls. I will contact vBSEO that there is a problem when using it. Truly a shame and hopefully, they will be able to find a fix for it because it's such a good mod. It just shows the url with the downloadtitle in it.
BUT.... the other error message is still present. I mean this one:
"Maximum Upload Limit would be Exceeded by this file. Try a smaller file."
It's really weird because most members don't encounter this problem but only some do. And those members never had a problem because. It just kicked in...
Any idea because it's kind of important that I fix it. My top uploader has this problem and I'm missing quite a few downloads now.
Thanks Jelle! And respect to the Dutch speaking lads!
