It is really concerning that wix don't perform thorough validation tests before they update their system.
About 10 days ago they made some update which has caused certain elements of wix code to just stop functioning all together.
This shows that wix do not have a proper validation test is place before they update their system to verify that all elements of the platform are still operational.
10 days later and still no statement from wix as to what has gone wrong.
Really unprofessional and worrying for the long term future of the platform.
