 * Hi !
 * Please help me. 1.0 was working fine. i upgraded to 1.1. wasnt working, removed,
   reinstalled 1.0 and now everytime, whether i use plain shortcode or shortcode
   with posttype(‘post’ or many postypes) i am getting this error 🙁
 * Warning: implode() [function.implode]: Invalid arguments passed in /home/jabulktb/
   public_html/new/wp-content/plugins/timeline-pro/index.php on line 482
 * What could this be ? If $posttype is only containing post then there will be 
   no commas or is not an array, hence its failing. Im not sure why now all of a
   sudden this is happening ?
 * How do i delete any settings that 1.1 created ? is it unregister_setting(timelinepro_setting_name)
   etc will this help

 * hi Loomy83
    we have removed shortcode attributes so if you define posttype=’post’
   or something like this in shortcode it will not work.
 * please use version 1.1 and create custom post “**Add New Timeline Pro**” and 
   see the shortcode at bottom please use this only like bellow
 * [timeline_pro id=”xxx” ]
 * so you don’t need define shortcode attributes in page, just change setting from
   exiting “timeline” you created.
 * ///////////////
    also please note that version 1.1 won’t create any option you
   mentioned, it will work with post meta’s
 * Thanks
