It's working now. I created another buyer account and logged in with this new account when prompted on the PayPal web page - that worked. Maybe, the first buyer account that was created for setting up the Sandbox is not the account that can be used for buying on PayPal test site.
Sandbox buyer account not working
I am following your tutorial https://wyday.com/limelm/help/automate-license-generation-with-paypal/ most of which works fine. When I click on Place My Order button, it successfully takes me to the test site store (https://www.sandbox.paypal.com/us/cgi-bin/webscr?cmd=........). But when I enter my buyer login/password, it always gives me the following message: "Please check your email address and password and try again"
Ive also tried the following two methods suggested by other users online but still the same error:Suggestion 1: Clear the cache on the browserSuggestion 2: First login to the Sandbox test site and keep that open, then open another tab in the same browser and login to your site and try the above tutorial.
I had created the PayPal Sandbox seller and buyer accounts that work fine as I can login to Sandbox.PayPal.com test site using seller account and can also login to Developer.PayPal.com using buyer account. Please help
Maybe, the first buyer account that was created for setting up the Sandbox is not the account that can be used for buying on PayPal test site.
That's correct.
