I upgraded from Fedora 13 to 15 on my way up to 17. I know I was out of date, hence the updates. After I made it to Fedora 15, I ran 'cleandupes'. This removed both Apache and MySQL. I reinstalled them via yum, but now I seem to get 500 status codes for EVERYTHING I visit on my box. I can't seem to find a reason WHY it is giving that error code though. Could someone please point me in a direction so that I can go look for the problem?
