Not Directing to Correct Page

Hey how's it going,

I'm currently working on a website and doing some testing on a domain. I've set everything up as usual but for some reason when I click a page in the navbar its going to something totally different (error page) but then I click it about 2 or three more times and it works. Anyone else have this problem? I wasn't sure if it was okay to post a link so I didn't but can if anyone can confirm that it ok to do so.

For example, say my domain is whatever.blah/my-page.html. It'll go to whatever.blah/service-page.html and I don't even have a service page.

Nevermind I figured it out :)

Might want to share the "figured it out" in case any of us run into the same problem.
