Hi there,
I've just updated to the latest version and installed the plugins, (running with latest EShop) tested with an existing coupon but received the invalid error message, tried editing to make sure the coupon was valid but it hangs on the loading ring, tried creating a new coupon, set-up worked but the new coupon doesn't work and on attempting to edit the new coupon the same issue of it hanging on the loading ring.
Your urgent help much appreciated!
