Social Media Shortcodes

Registers shortcodes for your posts, pages, or post types that display user profile links to various social media websites.

Many themes, as well as other plugins, provide shortcodes for layout options like multi-column-layouts, tabs, etc.
By default, Contact Form 7 forms can not include shortcodes provided by WordPress or third-party-plugins or -themes. 
It only processes its own shortcodes used to generate form elements.
This plugin enables the usage of external shortcodes inside Contact Form 7 Forms.

Contact Form 7 Shortcode Enabler

Resolve the problem perfectily. Congratulations!
