I created a test accounts in the sand box area of paypal and put the details into the the restricted content pro's setting page/ payments for a wordpress application such as Test API user name , test API password , and test API signiture. This is with a goal to set up paypal credit card payment on my site but I was not even able to login into the sandbox testing site for paypal with the details that were provided through my test sand box account. Could you help me to at least be able to login into the sand box testing site.
