I'm working on a wordpress website from another person before. That person made allot of double pages en etc. It's a total mess. So I thought to clean it up. But my original event page had an url like this: ".../events/categories-2/" so when I delete all other pages that called "categories", I changed the url to ".../events/categories/" but sinds that moment every page from my events or categories give me this warning:"Sorry no results were found.".
Does someone knows what to do in a situation like this? Do I need to start over? Because I would like to keep my settings from the event manager if that's possible.
Kind regards, Niels
