Thunderbird email won't connect

It worked yesterday & I had to do a restore and now it won't connect. It looks like it is going to connect & then stops.
Properties have been checked & targets etc.
Any suggestions please. Thanks.

Tools, Error console.
I'm guessing error messages appear there, perhaps?
