Using the Stack Overflow javascript authentication API, I get this error:

> Application Login Failure An error occurred while login into an
> application.
> 
> Error Details   
> error description: could not parse proxy url

I checked regarding this issue and I found a few URLs:

 - https://stackapps.com/questions/3631/bug-in-the-stackexchange-api-getting-could-not-parse-proxy-url-when-user-not
 - https://stackapps.com/questions/6166/resurfacing-bug-could-not-parse-proxy-url-error-message

Still I could not solve this.

Is there any other way apart from javascript Authentication to get an user's Stack Overflow reputation?

Please do help me on this.
