@tgchr you can disable the plugin by connecting to your server via FTP/SSH (or File Manager in your hosting CP) to the wp-content/plugins folder and remame yith-woocommerce-product-add-ons to yith-woocommerce-product-add-on or switch your PHP version to 5.4 temporarily, which will allow you to access the admin panel.

Resovled this, had a 301 redirect on /checkout to /cart for some reason. DOH!

Try switching to PHP 5.4 on your server. Your theme and wordpress version are most likely to be incompatible with PHP 7.0.2.
