Help with a URL shortening site

Hi there,

I am trying to set up a URL shortening site on Pet.pn with the following script

http://codecanyon.net/item/url-shortener-script-with-stats-page-/1429705

I've followed the readme but it comes up with a 500 Internal server error.
What have I done wrong? Can anyone help me?

Thanks

 

you should talk to the seller in codeconyon
try to install it in a diffrent domaine name just testing

 

He isn't replying to me so I dont know how to fix it

 

Contact the developer - it can be many different issues that may start as far back as the database to the actual wordpress framework.
