My Messages app out-of-blue started to complain that my GTalk credentials are being sent in non-secured manner.
Your name and password will be sent in a way that is not secure.
Do you still wish to connect to this server?
This was working all the time and I didn't change anything (including my network).
How do I fix it?
I've checked my Server Settings for GTalk account, but it seems my 'Use SSL' is greyed out, so I can't enable it.

Normally you've to just turn on the 'Use SSL' option (Preferences->Accounts->Google->Server Settings).
It's greyed out, because the option 'Automatically find server and port' is enabled. If the option is greyed as well, disable temporary the account then disable the option, then set the manual settings or try to click on 'Use Default Settings' option. You can use either 5222, 5223 or 443.
