We are having an issue with PayPal payment processor: “Pay with PayPal” button might redirect to the shipping details page.
We are working on this now.
At the moment we are figuring out the estimated scope of the affected stores. Please, stay tuned for the next update in 30 mins.
Please, keep in mind, that all your data (products, orders, customer details, store settings, etc) is safe and intact.
As a workaround you can use other payment gateways, please check the list of available gateways here: https://support.ecwid.com/hc/en-us/articles/360000730329
We are sorry for the downtime.
