Support » Plugin: Hierarchical Documentation » Warning Message that couldnt be understood how to recover from it

  • I am using the hierarchical-documentation plugin only to see a page full of warning messages. It demands to alter the tables(event_speakers, venues) by suggesting us with sql queries. And no data is viewed but only warning messages. i need help. This is the thing i get upon selecting any of the menus that are in the sidebar.

    ( ! ) Warning: mysql_real_escape_string(): Access denied for user ‘www-data’@’localhost’ (using password: NO) in /var/www/html/wordpress/wp-content/plugins/wp-mvc/core/models/mvc_database.php on line 34
