Attempting to send a private message to any name on my friends list results in this.
I write down the message, press enter to send, and no message gets sent. I do not receive messages either. All other forms of chat work. I've attempted messaging with private being in the chat box, and private being split and received the same results.
Anyone know if there is a fix to this?
Yes, cycle your online status from online, to friends only, to offline, and then back to where you usually keep it. If this doesn't work try logging out and back in. Those are the only fixes I know of for it.
EDIT:I didn't realise how old this post was, was just looking for any runescape gold bug problems I could help with.
