woocommerce issue

I just tested with wooCommmerce 2.5.5 with the storeFront theme on wordpress 4.4.2. It’s working properly. Is your wooCommerce theme free? I can give it a test.

the theme I use is https://yithemes.com/themes/wordpress/panthea-multi-purpose-e-commerce-theme/
I tested again. If I activate plugin, when I click on any product category, the products dissapear and also dissapear left sidebar.

I tested with the free version of panthea from the link. It’s working properly. See screenshot.

So, it might be another plugin that is not playing well with seo-friendly-images…
