I have set up multisite on an exisiting WP blog. After a few difficulties I managed to create a new sub-blog. My problem now is that I can see the new site but not login to the site admin (from any direction). Any attempt to go to .../WP-Admin just creates a huge url which eventually give the following error:
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
Request-URI Too Large
The requested URL's length exceeds the capacity limit for this server.
Any thoughts anyone?
