I'm currently running 2.1.5 and hitting this weird issue.
I can create and save Cart Price Rule .
However, in the Action Tab, I can't save the conditions in the area.
Apply the rule only to cart items matching the following conditions (leave blank for all items).
I tried different conditions and click Save. The page says it has been saved, however the conditions in that area are removed.
The Tab Condition works fine.
is anyone experiencing the same issue or know how to fix it ?
