We are also having this same issue. WP 6.4.3, WC 8.5.2, Addonify – WooCommerce Wishlist 2.0.9, WP Rocket 3.15.9.
Clicking ‘Add to wishlist’ results in “Something went wrong. <br>Title was not added to wishlist. Please refresh page and try again.”
We have excluded all seven JS files (verified paths are correct) from WP Rocket cash (minification, defer, and delay execution) as well as added the cookie exclusion “addonify-wishlist”. We’ve logged out and back in, and verified not working on multiple devices including Laptops and iPhones.
Website is currently being built and under construction. Address is https://www.marlincrawler.com/xn/ and requires log in at the moment so I created a temp Customer user log-in as follows, l/p: addonify/addonify. (I’ll delete this account afterwards)
Any help is appreciated, especially since we’re planning to launch the new site tomorrow night and are hoping to use your Wishlist plugin! ????
