How to remove non existing page? I have this page where I've put block views on it but I can't seem to remove it. It's not in the menu items.

I don't know what to show you here, so please if you need screenshots ask me.

Examples:

Ex 1

Ex 2
Example 1 is node 5 (http://erlinevanhijfte.be/node/5). go to it and delete it.
Example 2 is node 102 (http://erlinevanhijfte.be/node/102). go to it and delete it.  

To find the node I just looked at the page source which has a shortlink meta tag which shows the node id and also the body tag has a class which shows the node id
