Have you encountered this message in Gmail or any Google product you know you are logged in? You might have panicked the first time you saw it, and even felt disappointed once you read what Google says what it is.
Symptoms: Your Chat window shows this error:
‘Chat is disabled. You have been signed out of Gmail. You must sign back in to reenable chat.’
Solution: Clearing your browser’s cache and cookies usually resolves this error. For instructions go to Gmail Help
In some cases, it may be necessary to clear your cache more than once.
My Explanation
Being a frequent user though, I don’t think that is related to cache settings. If the solution above had worked for you, then that’s great. However, for others it may not, and you might also want to know more the reason behind this message.
My explanation for this error could not be valid, but this is just my observation for using Gmail account all the time. I have several Gmail accounts. One master account is used for other Google products and services. I also use several browsers: Internet Explorer, Firefox, Opera, and Google Chrome.
So first, in browsers with tabs, most of the time you are only allowed to logged into one Gmail account. If you are logged in to your master Gmail account in one tab, then you cannot logged into another Gmail account in the other.
You might say that that is a dumber. But what if you went to Google Reader, or Google Calendar in the other tab and realized that that is not the account you want to use. So you signed it out and signed in to another Google account. Once you go back to your Gmail tab where your Master account is, you will see the message that you are signed out from the account. That’s because you signed it out from other Google products that you used.
Uhm..
What I am trying to say is that your Gmail account is your logged in to other Google products, and all Google products are just in one account, and that is what you call your Google account–a universal log in. So if you sign out one Google product, the rest in other tabs will be signed out too.
(Example of Google products are: Google Docs, Google Reader, Google Calendar, Google Search, and Gmail)
Logging into Several Gmail/Google Accounts at the same time
The reason I am using several browsers is that I am logged in to different Google Accounts, and ‘Remember me in this computer’ are all enabled in these browsers. This allows me to save time logging into different accounts I use.
If you don’t want to download and install several browsers to help you multi-task then I suggest you use the Internet Explorer 6 version and make sure you don’t have the tabs in it. Some toolbars you install might have added a tab feature.
Unlike other browsers, Internet Explorer 6 allows me to log in simultaneously in two or more Google accounts. The difference is, it loads as a new window not a tab. I don’t know the real technical reason behind this, but that is just what I noticed.
Make sure when though you log in to Gmail or into any Google products using Internet Explorer 6, you did not click the ‘Remember me in this computer’. So that when you open a new window you are not logged in to any Google account.
(I am not sure if my suggestion will work in Internet Explorer 7 and 8. You can test them out.)
In Firefox, or Google Chrome, loading a new window to log in to another Gmail/Google account will not work. These browsers only allow you to log in to one Google account at the same time even if it is a new window.
