Seems to be a new issue, not affecting all pages. Maybe just those with a lot of content?
e.g.
https://stereo-untypical.com/products/q-acoustics-m20-powered-bookshelf-speakers
I’m using the Supply theme.
Scroll down to see it.
Help?!
A lot of images in this product description are loaded from https://essentiatechnology.ca/
Most sites do not like this, so may block their images from showing on your site.
For example, I see no images.
Document HTML code shows that it was initially done for WooCommerce site and looks like it was copy-pasted into your store. This is always problematic, because content like this usually depends on CSS (and sometimes JS) codes, which are specific to the originating platform.
Having said that – this particular problem can (most probably) be fixed by adding code like this to the Theme Settings=> Custom CSS in Customizer:
.rte .flex-viewport {
max-height: none;
}
That Theme CSS worked, many thanks Tim!
