I have been unable to 'send' replys to a PM initially, all was well, but for some reason, having typed my reply and pressed the send button, nothing is happening.
I'm not sure - I've been looking through the admin logs but nothing is flagging up as a problem. As a first try can you send me a PM and I'll see if I can reply.
the problem still exists with my original PM, but I have overcome it by starting a new PM and that and reply's to other PMs seems fine. Many thanks for investigating.
