After upgrading my site from (following directions as noted on the word press site) 2.5.1 to 2.6 I am unable to login to the admin section of the site. When credentials are entered, nothing happens. No 'sorry you used the wrong password' message, no redirect. It just stays on the main admin login page.
Now here's the kicker. If I go to the public face of the blog, I seem to be logged in but can access the site from a Safari for Windows browser. FF3 and IE 7 and IE 8 Beta do not work.
Not sure what else is needed. If someone would like to contact me I can show them my site.
Right now, I am unable to use Wordpress in a normal manner.
