Can't reply to PM with new forum

[Deadlock]

Can't see a setting at my side that's causing it, so looks like I'm just not able to reply to PM's any more?

But I read what is in your picture and I just started laughing when I read it.

I've now saw this appear when replying to other posts now, so isn't specific to replying to PM's.

Seems more like it's related to the logout problem every 5 minutes.
