I have a very strange problem with wordpress.
I have this kind of pages:
http://www.example.it/page/4
if I visit:
http://www.example.it/page/4?cat=1
I get the error 404 not found
If I visit:
http://www.example.it/page/4?catt=1
I can see the page correctly.
Why does the cat paramenter returns this problem?
Thanks
Cat is a parameter that is used internally by wordpress when parsing arguments. It is actually looking for a category of that kind.
A 404 will appear if no post has that category associated with that category ID.
If the category does exist then wordpress will redirect you to either a page or archive listing depending on what you have setup.
In short. Cat is reserved as a parameter.
