First I want to ask about using Smart Payment Buttons, is it safe 100% ?
I have been using them for a while suddenly today i see a problem that the buttons are not loading.
Uncaught Error: Attempted to load sdk version 5.0.63 on page, but version unknown already loaded.
To load this sdk alongside the existing version, please specify a different namespace in the script tag, e.g. , then use the paypal_sdk namespace in place of paypal in your code.
Uncaught TypeError: paypal.Buttons is not a function
