I'm trying to add the slider to the side but for some reason whenever I add an entry to the slider I get a page not found.
It still works when I haven't published it. Preview url: mydomain.com/?post_type=slideshow&p=2428&preview=true
When I publish it the domain is: mydomain.com/slideshow/do-you-get-many-new-customers-from-the-internet/ but all that I get is a page not found message.
What is the problem?
