Hi. I find out after last WooCommerce and xStore updates that I get visual bug on some single product pages. Single product page has big white empty space between price and add to cart button.
At first I think that problem is in plugin and I get this answer from the plugin developer:
You theme templates isn’t unfortunately compatible with WooCommerce 3.4x which results in the options showing twice. The white space you see is actually a second set of options, hidden. This happens because WooCommerce 3.4 changed the variation template and now the default hook that the options are being displayed on called woocommerce_before_add_to_cart_button is being executed twice. Once from your theme template and once from the new template of WooCommerce 3.4.
You can easily check this your self by switching to a default wp theme that doesn’t have custom WooCommerce templates.
You will have to ask the theme developer to update the theme’s WooCommerce templates.
Sorry, but WooCommerce TM Extra Product Options plugin author should take a closer look at your problem because it works the same way even with the default and official WooCommerce theme – Storefront https://gyazo.com/7b172d3ba7873eda30e502aaf248c50d
It means XStore theme is not the reason of the problem.
Actually, it’s the compatibility issue between Woocommerce Color or Image Variation Swatches and WooCommerce TM Extra Product Options plugins. Because when Woocommerce Color or Image Variation Swatches plugin is disabled problem disappears.
