Thought this was resolved...but I think there is a PHP version issue.
I was able to re-activate the plugin on my development VPS with no issue...so I backed up the entire working site from dev and moved to Production BlueHost Shared Hosting...BOOM! failed!
I deactivated/reactivated on shared hosting still fails with Error Code 500.
BlueHost Stack:
PHP Version 5.4.24
MySQL Version 5.5.42-37
Development VPS Stack:
PHP Version 5.4.45
MySQL Version 5.5.47-MariaDB
Keep in mind this site was working fine running on the BlueHost Shared running WP 4.2.5 Core and WP-Property 1.42.3.
