enable paypal sandbox

I’ve been trying to set up paypal sandbxo to test paypal payment gateway but perhaps I haven’t done this for a while. Before I can set it up easily but today afetr checking the “Enable Paypal Sandbox”, and “Enable IPN email notifications”, on Checkout page, Paypal never showed up.

Then i tred to get the API credentials:

Sandbox API username
Sandbox API password
Sandbox API signature

But when following the instructions to create a devloper business account on Paypal Sandbox page in order to get the credential, the sandbox page does not have a create a new account link, and I tried to go around to find a way to create a develop business account, all I got was lengthy sign up process asking me for from email address to business name, business address, business phone# etc etc etc even my social security number and it goes on and on..it just doesn’t look right.

Can someone please help. I just need to have Paypal show up on checkout so i can test payment.Thank you so much.
