Hi there,
Don't worry too much. With that error message, I can see that you changed the kBank field to "Oro". I think you made mistake in this step. I think you want to change the name to "Oro" (means "gold" in Spanish, right?) instead of the field.
Now you can fix by 3 steps:
- Turn off all hooks
- Go to kBank Settings page, change "Oro" back to "money" in "Money field" and change value of "Name of points" to "Oro"
- Turn hooks back on
If you don't know how to turn off hooks, take a look at this page:
