Ajax error

What’s the error?

In Backend I get only “Ajax error” in field where normaly should be the result
Where can I see more detail of the error?

If I deactivate the sells are shown correctly

You can check the Network tab of your browser developer tools to see if there’s an error for the ajax request. Otherwise take a look in your PHP logs in case there’s a fatal error occurring.

I think you’ll need to contact the author of the wc-product-customer-list-pro plugin, there’s nothing specific to Query Monitor here.

Best of luck!

OK, but if I disable Query Monitor than everything with wc-product-customer-list-pro works well.
