Fails, is loading

Same here, was working fine. Must be related to upgrading to WP 4.0. Hopefully they will release a fix and let us know.

Your site most likely has a more recent version of jQuery loading, and there’s currently a conflict with this plugin it seems. In the plugin folder, edit this file – /assets/js/yith_magnifier.min.js .

Change the two places it says b.browser to b.support and save the file. Hopefully the plugin author will release an update soon.

Thxs brianj, works perfect!
