So, I did leave it for a couple of days and today the problem has returned.

I'm still using the Vienna theme and that has worked perfectly since my last post in this thread. Since then, I have accessed the forum and made several posts here without any problem-

This evening, I logged into the forum and I was astonished to find all the formatting is haywire again.

Everything else works - all other forums and websites display perfectly - and I haven't even turned this computer off since I was last here.

I really haven't a clue as what is going on!
