 * I’m receiving an error with our plugin…
 * Warning: Illegal string offset ‘type’ in /home/customer/www/hbplaw.com/public_html/
   wp-content/plugins/simple-job-board/templates/v1/single-jobpost/job-application.
   php on line 53
 * Warning: array_diff_key(): Expected parameter 1 to be an array, string given 
   in /home/customer/www/hbplaw.com/public_html/wp-content/plugins/simple-job-board/
   admin/meta-boxes/class-simple-job-board-meta-box-job-application.php on line 
   74
 * Warning: Illegal string offset ‘type’ in /home/customer/www/hbplaw.com/public_html/
   wp-content/plugins/simple-job-board/admin/meta-boxes/class-simple-job-board-meta-
   box-job-application.php on line 88
 * You can see in the front end, one of the error codes, “Warning: Illegal string
   offset ‘type'”. The other two codes above are seen in the backend Page.
 * I don’t want to lose the postings that I’ve created so I’d hate to simply remove/
   reinstall the plugin. Any thoughts?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fwarning-array_diff_key%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_
