Fixing ‘Array to string conversion’ notice

First off, love your plugin, it’s part of most of my projects. I updated to version 2.1.5, today, and started receiving the following notice atop all of my CMS edit pages:

Array to string conversion {path to wck plugin}/wordpress-creation-kit-api/wordpress-creation-kit.php on line 181

When reviewing that line, I found that $this->args[‘post_type’] was the offender as it’s an array instead of a string. I simply modified it to reference the string ($this->args[‘post_type’][0]) instead of the array and that fixed things up.

Just wanted to flag for your dev team and anyone else that may run into this issue.
