static URL when browsing site

So I’m not sure how this happened but every page on my site displays the URL https://www.mysite.org despite the fact that it’s showing me the page that’s hosted at https://www.mysite.org/page2. Consequently, every page listed in my browser’s history points to the homepage. Obviously this isn’t good and doesn’t allow my visitors to navigate easily or return to a specific page at a later time.

I recently switched servers as I built the site on a test server and then installed in on the new server once done. Everything went smoothly with the transfer.

Any ideas on what might cause this behavior? I’m sure it’s a php file somewhere but wouldn’t know where to begin to look.
