Recoverable fatal error: Object of class WP_Error

this is on a regular taxonomy select tree field.

https://pastebin.com/hHxvh26L

the metabox: 'id' => $prefix . 'sections',

i commented out the admin column because it was throwing the error.

I havent tested with the other taxonomy metaboxes registered.

Here is a screenshot.. the error occurs on a post that doesnt have a taxonomy applied from the metabox... http://imgur.com/a/YKqK8

Here is the code for the taxonomy: https://pastebin.com/HKU4azBW

Hey thanks!!! that worked. Appreciate it. Great support!
