Twitter Login Issue

I have created an app on twitter and double checked the callback url is correct but I keep getting the same problem.

I get the error "Something's broken...
The page you have requested is currently unavailable due to an error."

I checked the log file and I have this:

Yeah I have done lots of googling. I have already read that and tried all the suggestions. I really don't understand whats going on. I have listed all possible callback urls in the APP and I have set the correct credentials in the forum. Strange.

Still can't find a solution for this problem though. It looks like plenty of others out there have the same problem as me. Something to do with the django package used for social auth.

So I found the error. When you give the settings for twitter it doesn't save it to the configuration file properly it converts it all to lowercase.
