After upgrading from 1.9.4.1 to 1.9.4.2, the LightCheckout extension from GoMage throws a blank page when proceed to checkout is clicked, on another site we manage we use FireCheckout from Swissups and it also throws a blank page on proceed to checkout..
The release notes on the latest upgrade from Magento say under “Known Issues” that Third-party checkout extensions and closed security cases will either not work securely or will not work at all, anyone else have this issue and is there a fix?
