cannot create new coupon

[ukfish1]

Several days ago I successfully created a coupon in VM.

I need to create another one but when I hit the green new button, I get a blank screen temporarily before the same page shows again https://www.gransteadsginger.co.uk/administrator/index.php?option=com_virtuemart&view=coupon

I also cannot now create new products or product categories.

VM: 3.8.2
Joomla: 3.9.18

Thanks, Paul

I just tested coupons in current VirtueMart 3.8.2 10325 J3.9.18 with no 3rd party VM extensions and had no issues creating them.

Turn on VM debug to see if that helps to workout the problem.

Hi

Thanks for getting back to me.

Funnily enough I just literally found out what the problem was. If I open the Joomla backend in Firefox, new coupons and new products cannot be created. If I open in Internt Explorer, thsy can be added OK.

Must be a problem with my local copy of Firefox.

Thanks again, Paul

I'm using Firefox 76.0.1 ..... it got updated today!
