Hey guys, first time posting here. I'm redoing my site and for some reason now the cart has this horrible page populating issue where giant black boxes appear while the page is loading. Sometimes they go away in about .5 seconds or so, but a lot of times, you have to refresh the page to make them disappear. The overlay boxes are different every time. I'm attaching a few photos for reference. They always seem to frame a subsection, image or text. I'm wondering if anyone's had the same issue or knows a fix for this.

For what it's worth, my site is built with Wordpress , and hosted on Hostinger. Payment processing, licensing and products are handled by Woo. I've added a lot of customizations and Woo overrides to the cart because the stock Woo cart is heinous to look at. Any help is appreciated, thanks :)
