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.

Thanks a lot, that was the problem! Now it works!
