 * In the last few days I’ve started to see the following notices and warnings when
   I try to search for a given post in the “All Posts” screen:
    Notice: Undefined
   index: post_series in /home/ms101admin/public_html/wp-content/plugins/organize-
   series/orgSeries-taxonomy.php on line 484
 * Warning: Cannot modify header information – headers already sent by (output started

   taxonomy.php:484) in /home/ms101admin/public_html/wp-admin/includes/misc.php 
   on line 1196

 * The site does not complete the search and only displays the above errors. I can
   still search from the front end and find the posts, but not from the admin backend.

 * Hi Doug,
 * Thanks for making your report. Can you please let me know:
 * – What version of WordPress are you running?
    – What version of Organize Series
   are you running? – Do you have any Organize Series Extensions/Add-ons running?
   If so, what versions? – What version of PHP is running on your server hosting
   your site?
 * Once I have that information I can use that to begin troubleshooting.
 * Thanks!
