The following blog on WPMU 1.2.3 has worked fine for the last 6 months:
http://apscms.net/departments/nutrition
Now when you try and view this site is goes to a "Not Found" error.
In addition, when trying to login to the blog directly at
http://apscms.net/departments/nutrition/wp-login.php the browser asks you to either save or open for edit the wp-login.php file.
Lastly, if I log in as administrator to http://apscms.net/departments/wp-admin and then try to go to the Backend of the blog above, it redirects to this page:
http://apscms.net/wp-login.php?action=auth&redirect_to=%2Fdepartments%2Fnutrition%2Fwp-admin%2F
According to the user of the blog, the last thing the person was doing was updating a post and changing the title of one of the pages in the blog.
All of the other blogs on the WPMU install work fine, except for this one.
Ideas about what happened? Some redirection error?
Thanks in advance for your help.
