Few of these somewhat saying the same thing.

Hello,

I am getting a few errors when paying with PayPal. Mainly all it does is load into a blank white screen.
I have tried this in serval browsers, cleared cache, different machine... ect.

Any thoughts?
Thanks

Hi,

Supposing that the buttons are displayed, if you click on the "PayPal" button and you don't get the PayPal payment popup, or you get a blank popup on top of the normal popup, it's likely you have a problem with the Cross Origin Opener Policy of your website. You need to configure your HTTP headers plugin, via the Joomla plugins manager and change its "Cross-Origin-Opener-Policy" setting to allow for it.

Thank you! That's exactly what is was.

I suggest some clarifications to the documentation page cited above.

You need to configure your System - HTTP Headers plugin, via the Joomla plugins manager. In the Plugin tab, change its "Cross-Origin-Opener-Policy" setting to "same-origin-allow-popups."
