Hello,
Once I set some price (payment fee) in the plugin and it worked. Then I modified the price again in the plugin and saved it, but in the cart the payment fee is still the price that I set first time. I tried to modify it many times without success. Also cancelled the cart, started the checkout again, but always the same. It does not work.
Can I do something in the database until you fix the bug?
Regards,
Thomas
