500 Internal Server Error

[powerchaos]

a 500 error can have to do with 2 things

or it is the htacces file that contains wrong code (depending on apache version and settings) or on wronge file permition ( php = 644 , cgi = 755 , folders = 755 or 777 )

first try to remove the htacces file , if you still get the 500 error then it is the file permition

if those are not the problem , then the php version is not good (do not run php as CGi , but as DSO )
also be sure to check if you use SUphp

if SUphp is enabled ... disable it
if php is not as DSO , then enable it ( can break down if you run php 5 and 4 at the same time )
