Hello,
To have only one Wishlist button displayed you need select “Use shortcode” for “Position” field in YIT Plugins > Wishlist > Settings tab.
To make text visible when hovering a button you need add this code in custom.css file:
a.add_to_wishlist.single_add_to_wishlist.button.alt:hover {
color: black;
}
How to create custom.css you can watch in this tutorial
To fix the issue with removing items from Wishlist page you need delete the file legenda/woocommerce/wishlist.php via FTP.
Could you please specify where you found the shortcode for “Manage Wishlist” page?
Thank you.
Regards,
Eva Kemp.
