 * Warning: usort() [function.usort]: The argument should be an array in /home/content/
   12/34567/html/website/wp-content/plugins/approval-workflow/class/workflow-list-

    Thanks for your help.

 * Hi there,
 * It is saying that because you have nothing in the workflow. It is not a critical
   error. I’ll work on clearing up that error message for the next release.

 * Follow up: I just submitted the code to svn. Watch for version 1.3.2. Also, as
   a side note, I would not recommend running WP_DEBUG on a production site.
