Can't connect to twitter


Hello people,

I’m trying to create a webbased application. On localhost almost everything works but if i upload this to the host it returns an internal server error.
I read that I’ve to add my domain as callback domain - and I did but this didn’t solve this problem.
And I use this project on a subdomain, could this be the problem?

I hope you can help me. Thanks in advance.
