I’ve gone through all of the plugins and it is indeed WooCommerce Memberships that’s causing the problem but it’s a theme specific issue. I’ve tried both the Twenty Sixteen theme by WordPress and Storefront by Automattic and everything displays perfectly with Memberships enabled – once I switch back to Royal the content on the product pages disappears. Memberships is a widely used official WooCommerce plugin so I can’t imagine a theme not supporting it, plus the changelog confirms that it’s PHP 7.2 compatible. Can you please take a closer look to see why Royal won’t work with Memberships in 7.2? Thanks!
