I wondered why the forum wasn't loading so checked the scripts - seems like the "fontawesome" site they use had been blocked / suspended by ICANN. Removing it from my script-blocker's "permitted" list restored the forum to life - just some buttons now have "placeholder" icons.
I presume that if you are having issues loading the site getting a script blocker will fix it.
