It's not linked to the update but to the HTTP Headers plugin settings. We have a section about it in the documentation for PayPal Checkout: [ www.hikashop.com/support/documentation/4...out-form.html#issues](https://www.hikashop.com/support/documentation/499-hikashop-payment-paypalcheckout-form.html#issues) > 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 System - HTTP Headers plugin, via the Joomla plugins manager. In its Plugin tab, change its "Cross-Origin-Opener-Policy" setting to "same-origin-allow-popups" Please [Log in](/login?return=aHR0cHM6Ly93d3cuaGlrYXNob3AuY29tL2ZvcnVtLzI1LWluc3RhbGwtdXBkYXRlLzkwOTkwMy1wYXlwYWwtY2hlY2tvdXQtc2FuZGJveC1hLW1vZGFsLXdpbmRvdy1vYnNjdXJlcy10aGUtZXBzLW9yLXBheXBhbC1kaWFsb2d1ZS1ib3g/dG1wbD1tYXJrZG93bg==) or [Create an account](/register) to join the conversation. - **[multiadmin38](/forum/user/56698-multiadmin38 "View multiadmin38's Profile")** - [![multiadmin38's Avatar](https://www.hikashop.com/media/kunena/core/svg/person.svg)](/forum/user/56698-multiadmin38 "View multiadmin38's Profile") Topic Author - [ Offline](/forum/user/56698-multiadmin38) Less More - Posts: 9 - Thank you received: 1 - - 11 months 2 weeks ago [\#369432](#369432) by [multiadmin38](/forum/user/56698-multiadmin38 "View multiadmin38's Profile") Replied by *[multiadmin38](/forum/user/56698-multiadmin38 "View multiadmin38's Profile")* on topic *[PayPal Checkout Sandbox - A modal window obscures the EPS or PayPal dialogue box](/forum/25-install-update/909903-paypal-checkout-sandbox-a-modal-window-obscures-the-eps-or-paypal-dialogue-box#369432 "-- HikaShop version -- : 6.0,0, -- Joomla version -- : 5.4.0 -- PHP version -- : 8.3.27 I use PayPal Checkout Sandbox in my test shop.
