Login shortcode not working in sidebar widget

@vipinkhandelwal,

Shortcodes, by default, don’t work in sidebars (usually). Many themes (but not all) add support for shortcodes in sidebar text widgets.

For those that don’t you can enable them pretty easily with some code:

add_filter('widget_text','do_shortcode');

Take a look at this article that explains in much more eloquent detail the problem and potential solutions: http://www.wpbeginner.com/wp-tutorials/how-to-use-shortcodes-in-your-wordpress-sidebar-widgets/

Hope that helps,
