On the front page and dashboard, the theme setting tab is not correctly linked to the settings page of the theme.

The standard code for this is:   

$settings = new theme_boost_admin_settingspage_tabs('themesettingboost', get_string('configtitle', 'theme_boost'));

If you change "themesettingboost" to anything else, i.e "themesettingboost2" and then use the settings tab, it will still take you to "themesettingboost", giving an error.

If you add an administration block to another page, such as admin/category.php?category=appearance and navigate to the setting, it works as expected.
