CHECKOUT PROBLEMS AFTER LATEST 1.9.4.2 UPGRADE

[paaulw]

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?

Yes the solution was to do with my version of PHP, I upgraded that to the latest PHP version 7.3 and all worked again, thank you Designcomplex
