I am trying to link my posts and pages internally. I am highlighting what I want to link and adding the url of that post in the link box. It seems to work until I click it, and then it brings up a page that says:
Sorry, but you are looking for something that isn't here.
Can anyone tell me what I am doing wrong? Sorry if it is a really obvious mistake, I have looked through the 'how to' section and either it's gone over my head or I couldn't find the right bit!
