Hi,

I'm only posting this because I've been on PC for some time and haven't had this happen as frequently as what's been going on in the last 24 hours.

I type responses to posts, and when I hit reply it says:

Failed to open page - Safari can't open the page because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait a few minutes then try again".

But my reply is completely vanished.

I'm not sure about these technical things - but here's my best shot:
