Hi Rainer,
Thanks for getting back to us. Please make sure whether your theme changes the <ul> <li> using any scripts or not.
I have tested this link: https://wptestbox.com/wishlist/shop/ using PageSpeed Insights.
You can test it yourself here: https://pagespeed.web.dev/analysis/https-wptestbox-com-wishlist-shop/xpq4us9qwv?form_factor=desktop
I found it like this:
List items (<li>) are contained within <ul>, <ol> or <menu> parent elements
Here is also a screenshot for your convenience: https://paste.pics/PNUFY
Thank You
Google Pagespeed Insights issue
Rainer Rösing
Hey, when running Google Pagespeed Insights I receive a accessibility issues related to Variation Swatches.
I think these issues would be easy to fix for you but could boost our SEO ranking.
List items (<li>) are not in parent <ul>, <ol>, or <menu> items.
Example: <li class=”woo-variation-swatches-variable-item-more”>
Would appreciate. Thanks
