Error displayed on landing page

Hi,

I am using Thrive Architect page builder with Flatsome theme (with Woocommerce integration)
However, using the Woo Notification Plugin ran into some minor issues on my landing pages. Any landing page built with Thrive Architect gets no background error on woocommerce notification…
I don’t know exactly why and how to solve them. Most of my other sites have the same problem…
Can someone help me?
Thank you very much!
