"Just move the files and change the Index Page Route"
Easy, I thought. Changed the files, changed the Page Route to portal/ as we use one.
Now, the portal loads as normal, go to click forums.... goes back to the portal...
Clicking any thread goes to the thread
Pretty much anything other than this forum list.
Edit: If I make a page route to another URL it loads up fine. Any ideas?
TLDR: /forums is redirecting to /, with nothing in htaccess
