Hello,
Same thing happens to me, when in the YITH Essential Kit for WooCommerce #1 and I click the links in the plugin card. It’s only this plugin.
With all plugins disabled except Woo, Snippets and Yith, in X Theme I get JS errors and in Twenty Sixteen I get a 404.
HTML of links:
<a href="<br />
<b>Notice</b>: Undefined variable: details_link in <b>/var/www/dev.domain.com/wp-content/plugins/yith-essential-kit-for-woocommerce-1/templates/yith-single-plugin.php</b> on line <b>145</b><br />
" class="thickbox plugin-icon"><img src="https://dev.domain.com/wp-content/plugins/yith-essential-kit-for-woocommerce-1/assets/images/plugins/yith-woocommerce-colors-labels-variations.jpg" data-pin-nopin="true"></a>
<h3><a href="<br />

" class="thickbox">YITH WooCommerce Color and Label Variations</a></h3>
And under X Theme JS errors:
