Can you please check the URL in the private content (please don’t publish where people can see) as Google says it will not index it as “clickable elements too close together” and “content wider than screen”. I don’t understand this. When I click on the “screenshot” of the Google page test tool, it shows what looks like the mega menu html which should only be loading for desktops. So the question is whether Woodmart is loading all the html and css code for the Mega Menu even on mobiles? Or is google not indexing this page for another reason?
Could you please check how it works with some default WordPress themes like TwentyTwenty or WooCommerce Storefront to understand is it our theme issue or not?
It looks like Google can’t “see” the CSS file on your website and that is why you got this error. Usually, it happens because of some wrong configuration of robots.txt or other problems with the server. But it can’t be influenced by the theme itself.
