Hi there
Sorry, I don’t understand what you mean with
Support keeps silence.
while this is the first topic you open on this manner.
Anyway, now that you reported, we’re happy to help as always ??
In your case it seems that search engines are indexing Add to Wishlist url in your pages.
Plugin includes rel="nofollow"
attribute in all its links, in order to avoid this kind of problem; so, my best guess is that your theme is overrding add-to-wishlist.php template, or it’s printing its own ATW buttons, and do not include that attribute.
I suggest you to search for add-to-wishlist.php or add-to-wishlist-button.php templates inside your theme or child theme folder, and if you can locate them to rename them add-to-wishlist.php.bak and add-to-wishlist-button.php.bak respectively.
Note that this will remvoe any customization applied by the theme to ATW button.
Note furthermore that even if you correctly re-enable rel="nofollow"
attribute, you may need to scan again the site to see the effects.
