Owner/Admin Permission MAJOR Bug

Hi, I have recently ran into server issue where all my core files were deleted from the folders on my server and only the database was left intact.

I have recreated the environment that the site was previously on and hooked it up to the saved Database that was not destroyed however when logging into my Administration account I am receiving the following error:

“You do not have sufficient permissions to access this page.”

Here is a screenshot of my Database/Site

Here is a copy of the WP-CONFIG file.

<?php

	define('ABSPATH', dirname(__FILE__) . '/');

Any help would be greatly appreciated.

PS: Could this be because the original WP installation before my sudden loss of data was pre 4.4.2 and one I try to recreate the files I installed WP 4.4.2 on top of a Database that was attached to the older version of WP?
