Can't login to Facebook Chat in Messages for El Capitan
In the last week or so, I have been unable to access my FaceBooik account for chatting via Messages for El Capitan.
I get the password prompt, enter the password, and it continues to appear. The settings are correct (they haven't changed) and the password is correct.
Other accounts are fine.
I can use other chat apps that support Facebook without problem.
A Keychain problem? There appears to be no First Aid function there anymore.
Peace,
