This is the first time I set up a supplier but whenever I try to pick up a Vendor I get "ErrorOops, something went wrong (Not Acceptable). Please try again. By default is selecting NMG Fragrances. Am I doing something wrong?
Someone else with the same issue?
Look at the browser Response to the last Request in Firebug or simiar browser debugger. I think you will find some debug or diagnostic output in the response that is causing an ajax response to puke.
