Health Check Error: Skin Customizations Were Detected

    Overview

    The Health Check wizard must be run when upgrading to evaluate whether your instance is suitable for upgrade. During the health check, various types of issues may be detected which can affect your ability to upgrade. This article will cover the “Skin customizations were detected” error reported by the health check.

    Resolution

    The generated error message will help determine the contents of the file causing the health check error. The code-level customization may need to be modified in order to behave as expected in the upgraded instance.

    The example error shown above was caused by a problem in the named file, ./custom/themes/custom.less. Customers with user interface-level customizations in their instance will need to validate and likely update these customizations in order to work with the new user interface in 7.11.

    Once the customizations have been validated and updated, please navigate to Admin > Repair and perform a “Quick Repair and Rebuild”. Then perform the health check again and click “Confirm” to bypass this health check error.
