I just installed the plugin and a few front-end issues occur.
For example, when I click 'close' on this. It doesn't close on this screenshot. https://i.imgur.com/vyyxypa.png
Also when I click on the product 'location' to edit the location. I get this empty combo box, that is not even clickable -> https://i.imgur.com/lqBWWeX.png
Thank you very much for your post.
What version of ATUM, WC, WP are you on and have you tried other browsers?
This seems site related, but I am sure we get to the bottom of it.
