We need more info in order to provide better service.

Are you just pasting button HTML into WordPress?  Is it basic or smart button code?  Are you using a plugin?  Are you using WooCommerce and some PayPal plugin for that?

What exactly are you doing within WordPress for PayPal payments, and what configuration steps have you gone through to get it working?

Also, have you tried clearing browser cache/cookies?

If you are using WooCommerce try using our PayPal for WooCommerce plugin. You shouldn't have any problems with it.
