Hey buddy
I had the same a couple days back & farjo is on the case,
I was able to send the message after re typing it rather than cut or copy & pasting.so if it's something small then thats worth a try.
Probably just some teething problems after moving servers or somethin.
P.s-i was doing the chicken dance the other day & my mate on his bike thought it was code for something on the road
,it does work though!
