I have successfully installed free lockbox software and planning to buy a licence but I am facing following problems
1. Front end member account sign up not working. Getting error message "an error occurred please try again"
2. Email sending is not working even after giving correct details for TLS/SSL/nil settings...Also, there is no documentation about email settings
3. While adding payment gateways, what parameters are needed to be added for PayPal and other payments. No info found there
