pmpro_cleanup_memberships_users_table.php

/**
 * This gist will force run the pmpro_cleanup_memberships_users_table()
 * function in PMPro. This function sets entries in the pmpro_memberships_users
 * table to 'incative' if either (a) the level has been deleted or (b) there is a
 * more recent active entry for the same level.
 *
 * IMPORTANT: Back up your database first.
 * NOTE: This script may not fix all issues with the memberships_users table due to bad imports/etc.
 * Add this code to a custom plugin, then visit /?cleanup_memberships_users_table=1
 * to kick off the script. Then remove the code from the custom plugin.
