Suddenly empty array when opening coupon / adding coupon

Hi,
i suddenly can't change any existing coupons or add any new. i see the select field, but if i select "coupon" it does nothing, it loads no further select fields as before.
do you know why this could be?
thanks and regards
andre

Hi Andre,

I do not know why this is happening. Did you recently upgrade? If so try clearing your browser cache and reloading the page. You may still be loading the old js file, which might be causing errors.

Hi, we think it´s because of the high number of products we have and the AJAX module is not able to load them. The old coupons still work, we just can not edit or make new ones.

I see. If you make edits to AwoCoupon, you can load the coupon entry screen. Here is a post that can help with that:
