For some inexplicable reason comments aren't being published today. I've no idea why this is happening. I've checked settings, rebooted and spend quite some time searching for an answer in Google.
My apologies to all those who have commented today. I have replied. Perhaps your comments will be published when the problem is resolved.
If anyone can help I'd be grateful.
Update: Comment are there now even although it's stating '0 comments', so something is happening and it seems I'm not alone. Good to know.
Latest Update 7.00am: Everything appears back to normal. Phew!
