I’m having the same issue, I posted this on discord:
There is a very annoying issue with the forums. Sometimes while im logged in, i would visite a page then i would no longer be able to click anything or scroll. All other pages face the same issue until I clear cookies and cache and relogin. Sometimes that wouldn’t solve it. I checked the page code and found out that a section with id=“d-splash” is causing this and if I delete it, I can browse again. But i would have to do that for every page
