How to set up paypal live?

Question

PHP

There was a problem when transferring paypal from the sandbox to the live version, I specified everything that was required, but after redirecting to the paypal page, the error
Your session has ended
We're sorry, but your session has ended. Your account hasn't been charged. Please go back to the merchant's site and check out again with PayPal.
for some reason, it goes to the page https://www.sandbox.paypal.com , although it is not listed anywhere.
Who knows what the problem is and how to connect the live version of paypal.
PS everything that has changed after the sandbox: login, password, signature, website (from sandbox to live)
