Instead of being all neat and tidy, I seem to just be on a text-only version, with tha names and amount of posts underlined in blue.

It's very hard to read, and understand where each post starts and finishes.

Classic IT Crowd answer - have you tried turning it off and on again???

It maybe can't cope with all the I LOVE LUCY threads.
and has decided it needs a break!!!
Ha Ha.....
