reset user role in an mu-plugin

user-role.php

<?php

/**
 * Instructions:
 *
 * 1. If you don't have a directory called wp-content/mu-plugins, create it
 * 2. Create a file at wp-content/mu-plugins/user-role.php
 * 3. Paste the entire contents of this gist into the user-role.php file
 * 4. Replace the value of $user_login ('boone1') with your user name
 * 5. Replace the value of $user_role ('editor') with your desired role. You probably want 'administrator'
 * 6. Save the file
 * 7. Load your website in a browser
 * 8. Now attempt to visit wp-admin. You should have full access again. Assuming you do, you should immediately delete the user-role.php file (or comment out the add_action() line at the bottom)
