shortcode processing filter of widgets

Thanks for leaving this comment. I updated to version 5.1.1 today and discovered that the contact form is no longer displaying on my site.

I use a shortcode to display it in a Custom HTML widget. Now all visitors see is the shortcode.

Is there any chance this can be fixed quickly by the developer(s)?

Just add the following filter to your theme’s functions.php file:

add_filter( 'widget_custom_html_content', 'do_shortcode' );

Make sure the shortcode is included in a general Text widget. Shortcodes don’t work in other types of widget like Custom HTML widget – Takayuki Miyoshi (CF7 plugin author).
