I installed a php script and its showing me a 500 internal sever error at [url removed, login to view] . If you go to the admin panel at [url removed, login to view] , I can acess all the features with no problems. Its only the main page thats causing the problem. I am very sure that my server supports the script. I believe its because of the .htaccess thats is conflicting.
You will need to get this fixed as soon as possible.
