conflicts with the theme “XStore”

The plugin conflicts with the theme “XStore | Highly Customizable WooCommerce Theme & WordPress” (more precisely with the “et core” plugin that the theme needs to work properly). The plugin is malfunctioning when the “et core” plugin is enabled. If you want to test and resolve the conflict between the two plugins, you can install the plugin on my site. If you need access to cpanel, I can give you access there as well.
Try with the “et core” plugin enabled, and with it disabled, to see what it looks like in both cases.
