When trying to login, the spinner spins indefinitely

[beyonda]

Using 2.1 RC1

When users try to login (click the 'login' link on the top bar), the login windows opens but the spinner just spinning infinitely like the screenshot.

I've tried on 3 different browsers; safari, chrome and IE and all the same.

The only way to login is go to 'website.com/login' address via address bar.

Cannot solve the problem at all.

Are you using Pretty URLs?

Are you using Pretty URLs?

Yes I am. So, that would be the cause!

It's definitely a known issue but I don't know if it's been fixed in the very latest version of Pretty URLs or not.

Problem solved, yet cannot use PrettyURL with SEO functionality on 2.1RC1

Thank you!
