Adding Coupon sends user to home page?

[andy871@.....com]

Hi,

When adding a coupon in the checkout page, upon clicking on the save button, the users are sent back to the home page.
When you go back to the checkout page, the coupon has been added and you can proceed as normal

Any idea why this may be happening & if its not OPC that is causing the issue any further ideas, would be very welcome.

Thanks
Andy

hello andy, can you try to enable "do not use ajax for coupons" within the display section? there is a small bug within the coupon even on the very latest version which i just discovered yesterday and will be fixed and released within the upcoming 259 version.
best regards, stan
