Paypal Developer/Sandbox new interface: cannot login with test accounts
paypal, paypal-sandbox
Solution
Once you validate and log in using your PayPal credentials, you can import your individual sandbox profiles. Prior to logging in to a specific sandbox account, you will have to clear your browser cache and cookies. I was having the same issue with both Chrome and Firefox. After clearing cache/cookies, I was able to log into to a sandbox profile without any issues.
If you do not clear C&C, you will receive the following error:
"This Sandbox email address is not available. Please enter another email address."
Thanks,
Problem
I'm having problems on sandbox.paypal.com login with my test accounts since they've changed the interface. I was forced to create a new account on developer.paypal.com (which is now a beta) and import my old test accounts. I've done that but none of the accounts work anymore! I cannot login the sandbox with my merchant account and purchases aren't working. Anyone has the same problem?
