The problem came from the plugis Autoptimize and Shortpixel. I disabled them, but this is not a solution for a long time.
I just updated Enfold and got a strange phenomenon. The sliders are shonw in Chrome, but not in Edge, Firefoz or mobile. I have no idea where to look for the error.
Could it be that the problem ist that these are posts in one case and WooCommerce products on the other?
If yes, what would be the solution?
So, if I have 4 sections I need to create 4 unction is_tree($pid) and stuff, or should I only add the page numbers?
