Can't enter Guild Chat text
Make sure to tick the box next to each Guild Chat channel accessed via the drop-down menu from the Guild Chat option (the gear above the chat box).
If you view the Guild roster of the Guild member you are trying to whisper, it should ‘fix’ the ‘offline’ anomaly.
Good luck.
Thanks for reply. The box is ticked but satill no Guild Chat text can be entered. I viewed the roster but still told playerI was trying to contact is not online
