Wordpress: You do not have sufficient permissions to access this page

You can use the following script to list all tables of your WordPress database:

<?php
require_once 'wp-config.php';

if ( ! mysql_connect( DB_HOST, DB_USER, DB_PASSWORD ) ) {
    echo 'Could not connect to mysql ' . mysql_error();
    exit;
}

$tables = mysql_list_tables( DB_NAME );
while( $table = mysql_fetch_row( $tables ) ) {
    echo $table[0] . '<br>';
}

Create a file named table.php (or any name) inside the WordPress files folder, paste this code and access it over the browser:

http://128.199.54.130/table.php

It should list all the tables in your WordPress database, make sure all of them are prefixed with wp_.

A few other things I noticed:

Your site URL is set to the IP address, to change this login to WP-Admin > Settings > General, set both WordPress Address (URL) and Site Address (URL) to http://yitzwoolf.com.

The www version of the site does not have a DNS record. In the DNS section of your DigitalOcean control panel, create a CNAME record as follows:

Don’t miss the dot at the end of the second text box.

Since you have not posted anything on WordPress yet, I would suggest giving ServerPilot.io a try. It is a hosted control panel which makes managing your server a lot easier. It installs only on a fresh server.

This sounds more like a file permission issue. Make sure the file permission are set properly all files should have a 644 and folders should be 755.

if you need assistance repairing permissions I would look here. They have a script taht set the proper wordpress permissions.
