Hi
In prestashop 1.7.8.x, prestashop use microdata to show schema.
With builder of appagebuilder and review of leofeature
You will get error with schema.
Please follow my guide to fix:
1. update module appagebuilder to 2.4.5
2. Update moduel leo feature to 2.2.2
after copy module, please update or reset this module.
3. access back-office > Ap PageBuilder menu in left > Ap Module Configuration
scrool to Back-up and Update tab > Update and Correct Tpl for schema
