Files below local/share/check_mk/web/htdocs are served instead of the shipped files with the same path. Copies of shipped files, for example of a whole theme to replace a single logo, are not updated together with Checkmk. After an update, the outdated style sheets of the older version were still delivered, which could break the layout of the user interface, e.g. the search of the main menu covering the navigation bar.

Analyze configuration now warns about local style sheets and scripts that override shipped files. Other local files, e.g. replaced logos, are not reported. Remove the copies you do not need. To customize the look of the user interface, use a theme of your own instead of overriding the shipped themes.
