 * I’ve narrowed it down, when I have Vegas and Video Thumbnails active and then
   try to Save or Update my page I get this:
 * Warning: Cannot modify header information – headers already sent by (output started

 * This looks like a bug in the Vegas Slider shortcode. While this information may
   not be useful to you, it should hopefully help the developer. Shortcode callbacks
   should create output using return and not echo, more info here: [http://codex.wordpress.org/Shortcode_API#Output](http://codex.wordpress.org/Shortcode_API#Output)

 * Next week is my planned release date for the newer version of the plugin. I’m
   just working out kinks at this point and I’ve addressed the issue of returning
   vs echoing the shortcode. Keep your eyes peeled.
