Solution:
The user was using the outdated PHP version, upgrading the PHP version does the trick.

Problem: I have inserted a shortcode in a WYSIWYG field's contents, but when I try to output the WYSIWYG field using PHP, the shortcode is simply written to the page. I would like to echo the WYSIWYG field and render the shortcodes in its content.

Solution: Use the do_shortcode function to parse the WYSIWYG field contents and render the interior shortcodes:

$field = get_post_meta(12345, 'wpcf-wysiwyg', true);
echo do_shortcode($field);
