Blackberry Facebook Messenger App displays "connection error" message
So out of the blue, my Facebook Messenger App stopped working. When I go on the hope page it says no messages and when I try to refresh it a message saying "connection error" shows up. If I try and send a message to someone from that app it works fine but if I quit the conversation there is no way I can find it again because it says I have no messages.
I've tried rebooting my phone (blackberry curve 9300), logging out of the app and loggin back in. I even deleted the app and installed it again and it still isn't working.
HELP !
