PM not sending

[BluePancakes]

Apologies if this is in the wrong section. I received my first PM on this site last night. I tried to reply in the box, but every time I click "send from bluepancakes" a pop-up box comes up that is entirely blank, other than the "ok" to click. If I click that, the pop-up box goes, but the PM hasn't sent. If I don't click on it, nothing happens at all.

I've tried to attach a picture of what is happening. It's probably something really obvious that I'm missing, but I just can't tell what...

Help, please!
