I left my website alone for a while, and have come back every so often in my browser of choice (Firefox) to make sure everything looks OK. I just got a call from a friend who said my entire site is down. He's using IE. So I fired up IE and sure enough, IE is prompting a download for every PHP page I've tried accessing. Here is the message of the prompt:
Do you want to open or save this file?

[x] Always ask before opening this type of file
While files from the Internet can be useful, some files can
potentially harm your computer. If you do not trust the source,

I don't even know where to begin troubleshooting this. If you have any advice, please let me know! Thank you in advance.
