“Array to string conversion” PHP error

Hi, first of all, thanks for this super helpful free plugin!

I was just looking through our production error logs today and noticed this reoccurring error message. Here’s the stack trace:

PHP Notice: Array to string conversion in /…/wp-content/plugins/wp-job-manager/includes/forms/class-wp-job-manager-form-submit-job.php on line 523
PHP Stack trace:

PHP 11. implode() /…/wp-content/plugins/wp-job-manager/includes/forms/class-wp-job-manager-form-submit-job.php:523

My best guess is that $job_slug is occasionally a multi-dimensional array.

Thanks for looking into this!
