WordPress Login Not Working From Subsites

When I create new blogs under Multisite, everything works EXCEPT for the link for users to log in to the system to post on each of the blogs we create. When the link is clicked, we get the following comment in the web browser: “Too many redirects occurred trying to open ‘http://teach.wpcc.edu/david/wp-login.php” (an example of the link). This might occur if you open a page that is redirected to open another page which then is redirected to open the original page.” I’m guessing this has something to do with the htaccess file being set up incorrectly. I understand that WordPress sends users to a main login for the entire installation of Multisite when the login link is clicked and that I as the admin then have to move them into the proper blog after registration.

Why is it that the setup for the blogs work fine, but this link doesn’t? Do I have to adjust something in the htaccess file for it to work correctly?
