I am a real newbie, yet I am running a web site that has become somewhat popular fairly quickly. I was thinking that I would have time to learn, but I am in one trial by fire after another. We have Apache 2 running on a hosted 64 bit Suse Linux machine. Right now we are exepriencing something wierd. When some of our users try to download a file, they get HTML, not the correct file type. This does not happen with all users, as far as I can tell, and (in tests) is inconsistent from machine to machine. Everything worked fine for about 2-3 months. Then we implemented a set of PHP scripts for controlling password sharing and, boom, problems. I don't even know how to think about this! Could it be the scripts have caused the problem? If so, why does it not affect all of our users? If not the scripts, then what? All advice gladly taken. Thank you.
