Joomla 4 and Joomla 5 Note

If you are using Joomla 4.0+, it has a plugin called System - HTTP Headers . By default, that plugin will prevent the popup window to allow users to pay using their PayPal account. To prevent that issue, you will need to edit the plugin, change the Cross-Origin-Opener-Policy parameter to same-origin-allow-popups and it will work well
