QUESTION third party short codes in custom php not executing

[twright]

I have a custom php based web form that I use a Woody snippet to embed the form in a WP page. Formatting on the page is accomplished using Shortcode-Ultimate shortcodes. This has worked fine for years. recently it was noticed that the SU shortcodes are no longer being recognized. The "Execute shortcodes in snippets" option is checked in Woody. The SU formatting works fine on another page that is a standard WP page, no Woody snippet.

I've also now added a Woody Snippet to the custom php webform page to see if it would work. But fails. Screen shot in second attachment.

<?php
echo "Testing";

Any thoughts?
