Since late last Friday (21st January), or possibly early Saturday morning, it would appear that some members are experiencing a range of issues with page loads and using the chat rooms, e.g. PM's do not work, can only send one message, can’t get to other rooms etc. etc.
The common factor with all the members, who have reported these issues, is that they use BT fast fibre 990 (or similar) or the package BT call Halo 3.
The development team are investigating and have posted this on the support open ticket page:
'We're investigating an issue relating to BT Internet / EE users experiencing intermittent page load problems or chatroom disconnections. Some users have found switching from Safari to Chrome resolves the problem. Although we believe the issue is out of our hands, our team are looking for solutions.'
