Hello,
Please follow this article – https://support.rightpress.net/hc/en-us/articles/4406554199953
Here is a reply from other customer with the same problem: “I saw other users had complained about the same thing in the comments section and saw that the developers linked to an article about how to handle the problem with the plugin once it’s been hacked. What helped was importing a plain settings file that the developers provide in that article. The problem is solved for me.”
Check other comments of the plugin page – https://codecanyon.net/item/woocommerce-dynamic-pricing-discounts/7119279/comments If the solution doesn’t works for you, but it should, post comment on the plugin page.
Regards
