Comment:

 A redirect is just a header that gets sent to the browser. If headers have
 already been sent (stated in your php warning, presumably due to all of
 the html output that occurs before shortcodes in the post content are
 processed) then there's no guarantee the client will respect subsequent
 headers.

 The fact that a redirect in a shortcodes handler ever worked in the past
 is probably luck more than anything else, and probably didn't work for all
 visitors to your site.

 Are you calling `exit` after `wp_redirect()`?
