Autoposting to Google+

I have been autoposting to Google+ for several years without any problems. This morning I changed the settings to post to an additional type of post and immediately started getting the following error message:

 Testing ...

    [pgID] => 
    [isPosted] => 0

)

I have followed the instructions on the link https://www.nextscripts.com/nxsfaq/how-to-unlock-google/ and also created a new Google+ account without any success.

Does NextScripts not work anymore with Google+?

Please help.
