I was trying to create a payment module for opencart. When i tried to save the details in settings page, it's giving me the error "Permission Denied!" even though I was logged in as a administrator.
Can anyone help me in this?
You need to set yourself with permissions. Go to
SYSTEM > USERS > USER GROUPS
in the admin panel, click EDIT next to your user group, then make sure the boxes are checked next to payment/your-payment-name-here (or just click Select All Under both boxes)
