I went back to the old folder names and the category links still won't work.

this doesn't respond, but everything else on the site works
[u]http://localhost/events/blogs/itEvents.php/someCategoryName/[/u]

This is driving me crazy. Could it be a folder rights issue? Does the code that handles the category name extraction from the url need to write to a file? Is a page continueally loading itself? I am grasping for straws now.

This is the error message Firefox give when clicking a category link to show all posts associated to that category.

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

I forgot to give an example of other links that WORK

This works fine (view all posts for May 2008)
[u]http://localhost/events/blogs/itEvents.php/2008/05/[/u]

This does NOT work (never responds)
[u]http://localhost/events/blogs/itEvents.php/someCategoryName/[/u]

What files are in the "someCategoryName" directory?

I started over from scratch. I don't know what was wrong, but at least it's fixed now.
