I'm just recently done an install of 2.3.2. I'm getting 404 and Internal Server Errors when trying to add a category.
The Apache logs show this:
184.108.40.206 - - [04/Jan/2008:09:02:56 -0500] "GET /wp-admin/categories.php HTTP/1.1" 200 5979 "-" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:220.127.116.11) Gecko/20071127 Firefox/18.104.22.168"

When I add a category, this is the error that I get:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, email@example.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

I've tried the mod_security fixes that have been posted, but still getting the errors.
