One of my users all of a sudden cannot post new topics or respond to any topic (she can't send PM's either, etc). Here is her description of what is happening:

I respond and type messages, but when I go to send them, it pops up and says "You must Type a Message" and all the stuff is gone that I just typed.

Any ideas?

Please read this=>here

And if they can't private message other members,check this please:

Go to the member's profile Via Administration Panel=>Scroll down to Special admin-only fields=>Can send Private Messages=>Make sure that the option yes is ticked=>if it isn't,change it,and press the save button

Thanks for the reply but that is not the issue. This isn't a new member and it is only happening to her (not the whole forum). Everyone else is able to respond just fine. I did check her profile and she is set up correctly to send PM's.

check in her the acp profile.
admin panel>user/groups search for the member then click her name and check in the profile there.

What am I checking for in her profile? Everything there looks normal to me - she looks exactly like every other user on my forum.

Make her clean out her history cache etc....
