    Strip shortcodes on home page but not on single or archive pages
    When viewing posts ‘home’ page, strip all shortcodes, but on other pages, such as single.php, do not strip the shortcodes.

    /**
     * Remove shortcodes if we are on the home page
     *
     * @param string $content Post content.
     * @return string (Maybe) modified post content.

    It is worth to note that this function removes only those shortcodes which are registered at the moment of the processing of this function. If there are any “leftovers” shortcodes, like those which were added by some plugin but that plugin is not active anymore, this function WILL NOT strip them. It is possible to check which shortcodes may and will be stripped with the help of this filter strip_shortcodes_tagnames
