Changing Vendor not loading list of Vendors

When I’m editing a product and I want to change the Vendor, the Search box comes up but is continuously “Loading” with the throbber spinning around.

Searching for any other vendor yields no results and it never stops Loading (have left it for half an hour to no avail).

I have multiple Active vendors, and products have been added to some Vendors, however I cannot change the vendor when editing a product.

This problem extends to selecting a Vendor for Pages, Forms, etc too.

It is required to examine issue on your installation. If you are familiar with the developer console of your browser, check the response of the request after the “loading” label is shown. Or contact CS-Cart support team
