My site is already released to the public and I don't want to cause a disservice by upgrading the PageBuilder version to 3.8.x. You can try it yourself by installing the downloadable package "Quickstart Joomla 4" (salon_quickstart_j4_v2.0.0.zip) from your website. Once installed, upgrade PageBuilder to version 3.8.x and you will see that the Slideshow (full) add-on is displayed white on the public side. If it's a problem, try it in your LAMP environment, I can create an empty test LAMP environment where I will install the quickstart package

There is a solution for it. Please try it on your localhost. Go to this file: templates/shaper_salon/js/owl.carousel.min.js and find this string andSelf and change it to addBack. You will find it 6 times. Change all the 6 string. It should solve the issue.

Perfect! now works fine

remember to fix the download pack regards
