..../wp-admin/supporter.php#supporter-php constant refreshing

Hi,

I'm testing on of my sites after upgrading to 3.1.

I created a new blog like any new user would and selected being interested in the supporter features during sign-up.

I then signed in at ../wp-admin and was taken to ../wp-admin/supporter.php#supporter-php

the page loads and refreshes and loads and refreshes in loop.

Any ideas what the problem may be?

many thanks,

Ralf
