404 page with "Sorry, an error occurred or this page isn't available" after loginIssue Often, post NewYork release, some customers experience this issue: When logging in, instead of being directed to the home page, they're seeing a white page with the message Sorry, an error occurred or this page isn't available This happens because the login page is trying to load an image (.iix) which does not exist in the instance, for example, usually the image of the banner which is defined in the system property glide.product.image.light. This property defines the Banner image for UI16. In order to fix this issue, you need to point the glide.product.image.light to an existing image on the instance. For that purpose, one can see which image is set or define another one by navigating to System Properties > Basic Configuration UI16, and on to the field Banner image for UI16, you can upload a new image.
