My first week trying to develop a DNN portal, I think I've crushed the configuration.  I was trying to set the default home page for the portal I was working on, so under the Site Settings, Advanced Settings, Page Management, I tried pointing the pages to my home page.  Unfortunately, it looks like all I succeeded in doing was to create some kind of giant loop - in IE, it just times out without getting me to any kind of page and in Firefox, I get an error that says "Firefox has detected that the server is redirecting the request for this address in a way that will never complete."

The only option I could think of was to go in and modify the entry for the portal in the dnn_PORTALS table, but don't quite know what to change it to based on the info in the dnn_TABS table. 

Is there some way to fix this?  Any suggestions would be most appreciated!
