I've several files, range from 1.5MB to 10MB but all the downloads stop at 1.1MB, tried IE and mozilla, both stop at the same time.
Any idea what's going on?
I'm not sure exactly what you are asking about. You are running a server and all attempted downloads from that server die at 1.1MB transferred? What do your apache logs indicate? Have you tested from multiple locations?
If you could PM a link to a test file to download, I'd like to help you out. I'll need the resulting log entries as well, once the download has completed, if that would be ok. Please don't post my IP publically on these forums, however!
