Hello,
Thanks for using our theme.
1) Download etheme.min.js from this page https://dropmefiles.com/rTQmu and reupload it into wp-content/themes/xstore/js folder via FTP.
2) As we can see, you uploaded images in different dimensions – https://prnt.sc/10qnozt https://prnt.sc/10qnpd0 It is recommended to use a graphics editor and prepare product images (make them the same size) before uploading to your media gallery.
