I paid yesterday but only noticed today that no one can comment at all, not even I can comment (logged in as admin on my wordpress site).
I'd added some IP addresses to block, so removed them all then deactivated and re-activated and every comment I try to post gives the message 'You are blocked! Contact me if you are wrongly blocked.'. Someone else also emailed to say they'd had the same issue.
Everything is default, there are no blocked Ip addresses, no blocked countries etc.
Not very impressed.
