I have a wierd problem:
On my site www.cpfc.org - I upgraded PHP last night as WHM was reporting that I was running an insecure apache config.
I rebuilt apache/php without getting an error however when I went to www.cpfc.org I was prompted to see if I wanted to download the file of type PHP - this happened in both mozilla and firefox. My index page was php but ALL other php pages were displaying ok.
After much investifgation I deleted my browser cache and made sure my web browser was requesting a fresh copy of every page and the problem went away for me however now I am getting loads of complaints of people getting prompted to download the index page.
Really wierd.
So to rule out PHP - I converted the index page to static HTML but the problem still occurs. I have also added to cache tags to the new html page but still people are reporting that they are prompted to download the homepage.
Anyone got any ideas?
