[wcs] shortcode isn't working, but [wcs layout=list] is…

Same problem here, did the shortcode change with v3?

Hey Guys,
I noticed that one of the .js files having to do with Calendar view showed in the WP Editor as (inactive) This seems to have fixed it:
(from this thread:https://wordpress.org/support/topic/wpcr-js-and-css-files-are-inactive?replies=7)

In your theme files, header.php , you need to add <?php wp_head(); ?> to the file on the line right before </head>

In footer.php , you need to add <?php wp_footer(): ?> to the file on the line right before </body>

This should fix the problem with any theme that does not use the proper WP hooks.
i hope this helps!
