When I enable the option “Ignore cache” the plugin stops displaying the wishlist icon on both the archive and single product page. My caching plugin is WP Rocket.
I have reset the cache after enabling the option.
Would it be possible for you to create/share an admin account to your server (WP and preferably FTP), so I could login and check what’s going on? If that’s the case, please send a message to [email protected]
