Conflict with other plugin

Hi everyone,
I’m using this plugin and it was working perfectly but when I installed another plugin (WPC Smart Quick View for WooCommerce) something went wrong, it seems that the two conflict.
Now if I try to edit my Layout (All Grid > Edit) it redirects me to a blank page and not to the edit page of my layout. If I deactivate the “WPC Smart Quick View for WooCommerce” plugin everything goes back to working properly.

Can anyone help me resolve this conflict?
Thanks ??
