With this article, I am going to show you how to fix Error User Settings Not Initialized. When migrate to SharePoint 2013, one user had the error whereby every time they loaded SharePoint they got the error “Error: User Settings Not Initialized”.
To fix that error, first you must open the User Profile Service Application from Central Administration. And then, click on Manage User Profiles and search for the affected user. Next step, Edit My Profile.
Next step, Scroll down to the bottom of the profile screen and tick Always use my personal settings and select the appropriate locale. Next, tick Use language and regional settings. Then, Click the Save button and close.
