This problem has caused me significant heartburn. RSS Feeds will work for a while, and then out of the blue, WordPress suffers from a problem that causes:
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
What tends to fix this is dropping the present database from MySQL and reinstalling an older backup of the database. However this is apparently not a permanent solution and over time, it reverts back to this error message.
It seems to happen on it's own.
