I am using the site **** as a guide
to develop my first paypal link.
when the call to sandbox is made I am getting the following errors
1. [Error] Viewport argument key "minimal-ui" not recognized and ignored. (home, line 70) (I don't think this matters)
2. [Error] Refused to load **** because it does not appear in the script-src directive of the Content Security Policy.
Error 2 I can't get past.
The call to sandbox is
header('location:****);
I would welcome any suggestions
