Thank you for the quick response.
Unfortunately the client doesn’t have a traditional login/register on the website.
It’s triggered when the user is attempting to leave a review inside inner pages.
Here is a URL to an inner page, if you scroll to the bottom, you’ll see a review box on the left, with stars below the text area.
Clicking anywhere on it will trigger a popup with login options, Gmail and Facebook.
Only the Gmail option is operational at the moment.
Thank you for the assistance.
