Also it seems the original main site has also disappeared.

I'm guessing that in the blind panic to revert back to the old theme something went wrong and we're now stuck with the default MyBB theme.
It also seems that the domain has been set to redirect directly to the forum rather than the main site, it's still there, you just have to access it directly 
For example, https://northeastbuses.co.uk/fleet/ still takes you to the fleet list.

At least everything is still fine on the Tapatalk app, which I mostly use anyway!
