Sure thing...
So my issue was using a Chrome browser, to which I was signed in on my phone and laptops.
The Off Topic section was inaccessible if I was signed into VT. If I logged out there was no issue.
Following the guidance on this page, I cleared the cache and cookies using the "History" option in my browser settings. This didn't work.
I then ticked the box in the "Advanced" tab of the "History" option that allowed me to clear "Site Settings".
Site works perfectly now, and seems to be quicker to load. Hope this helps.
