adultvideoscript script

I am trying to setup avs "adultvideoscript v 4.0" on my shared hosting "abelohost."

I did everything but I am getting this error

"This page isn’t working

…….com is currently unable to handle this request. HTTP ERROR 500"

when i added this code "php_value display_errors" to the .htacess file, i got this message

"Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request……"

Hope anyone can help me
