I did a manual upgrade from 2.0.5 to 2.8.4 carefully following the instructions here https://codex.www.ads-software.com/Upgrading_WordPress_Extended . When I was done, I also got the ‘You do not have sufficient permissions to access this page’ message on all wp-admin pages when logging in as admin. Removing the four ‘security’ keys AUTH_KEY, SECURE_AUTH_KEY, LOGGED_IN_KEY, and NONCE_KEY from wp-config.php was the only thing that allowed me to login. :/
Anyone have any suggestions on how to keep these security features and still maintain access?
