Bit of a strange one, please help.
I have used Mozilla T'bird for years and currently have six different gmail accounts ........................ don't ask!
Everything has been good until today when one of my accounts has suddenly become inaccessible, even though I know I have messages there.
All I get is the attached error message;
When I click on that account it only shows an inbox when the account 'expands'.
It used to be like the other accounts in that it had many other folders such as junk, spam, sent mail, deleted etc., etc..
Now it just has an inbox.When I click on that it shows up as empty and I get the above error message.
The error message is always the same except the number changes.
Thanks in advance,
