Bad value #widget-system_information .panel-footer for attribute href on element a: Illegal character in fragment: not a URL code point. Fix the widget config/wrench icon href. Add matching widgetname id tag to widgets configuration panel div element.
Note: Thermal Sensors widget config panel already had a different id tag. Couldn't find anything that referenced it though. If that is correct then it should be safe to change it to widgetname to be consistent with the other widgets.
