Invalid closure message

I finally found a fix. The error seems to be gmail trying to take you to re-enter your password for that account but it glitches. I followed the instructions on this site to force the re-login page to appear and it works again for several days. Only happens for one gmail account of the 3 we have, no idea why.

Can you send us a screenshot of that message, so that we can try to help you?
