there, Am trying to integrate the Google+ plugin on my site

Hi there,

Am trying to integrate the Google+ plugin on my site http://www.players.abbeybasketball.com

But cannot for the life of me get it to work.

I can't authenticate the Google+ app settings which I assume is what is causing the problems. Every time I click authenticate, it either says Bad Request with 400 error, or invalid.

Any suggestions?

Thankss
