Whole Site Down – 500 Error – After Update!!!

After just updating to the latest 6.4.8 version my whole webstore crashed with a 500 error!

This happened directly after the update so I had to revert to 6.4.7 to make it work again, this means there’s something in the latest version that’s crashing my websites which are using this plugin.

I can’t troubleshoot this as all my websites are live webshops but I do wanted to let you guys know that the latest update crashed all my websites.
