I was building a page with bunch of links in it in wordpress 2. When I clicked on create page link I got a 404 error.
After a lot of time investigating and removing the links in the page one by one, I found the problem only happen when I am linking to anything that ends with /stats/
I tried this in two different installation of WordPress and got the same problem.
Try creating a new page or edit and existing page and link to : http://www.YourSiteOrAnythingYouWant.com/stats/
anything that end with /stats/ and see what happen.
Am I the only one with the problem?
