Thank you this worked.

Hi Nick, Thank you, I put the site live and saw it panicked.  I can go ahead and  put the site live now.  Kind regards.

  This appeared on the live site as I scrolled, it's just there. How do I remove it please and thank you?   

Thank you

When I view my product page, this blank block appears along with what looks like a pop-up with Action, but when I click it does nothing. Despite my best efforts, I am unable to locate the blank block. I don't understand what I'm missing.
