Why are pictures not scrolling in woocomerce galleries?

Question

WordPress

link to the site: pavelcdn.ru/5txe
here on the screenshot

there should be arrows
, but for some reason they are not there, even if you turn on the display of the block in css, there will be only 1 picture, that is, there is nothing to scroll through, they don’t get depleted in one gallery
even put another plugin didn't help. The thing is that when I just put the topic, everything worked. I didn’t climb into the theme code as well as plugins (only minor css edits),
help with advice where to look for a cant?
ps tried to turn off the plugins, I thought the conflict, nothing has changed.

Answer 1

If the plugin is Easy FancyBox, then:
Settings - Media files - Scroll down to the Gallery section - Autogallery - Select the desired function in the drop-down list (Wordpress galleries only).
