Ok, I've been working with wordpress for quite a while now, even getting into much tweaking. However something just happened that I can't even figure out how.
I was working on a page and suddenly, my entire wordpress site was unaccessible (front and back ends). I emailed my host thinking it was their issue, and they quickly responded saying that the issue had been resolved and it was functioning fine on their end. So I checked and was able to see my home page and the back-end, but I get a NOT FOUND 404 error when I try to go to any other page of my site by link or typing the url.
The links are correct and it has to be something more because I am getting the basic 404 page even though I have a 404.php page.
So I am just at a loss here. Any help would be amazing, I'm on some time restraints here.
Thanks in advance,
