So,  you have also faced the same problem like me after changing the default wordpress table prefix from wp_ to something else. Let’s see how I solved the problem!

After installing the WSD security plugin this morning, it suggested me to changed the default wordpress table prefix to make my wp website more secure. I did so and then when I tried “/wp-admin” I got this stupid error “You do not have sufficient permissions to access this page.” Nothing worked except the front-end site.

Here is the solution to for this problem:

Step 1:

I entered phpmyadmin and took a backup of the website.

Step 2:

My old wordpress table prefix was “wp_” and I changed this to “wpkh_”

The following meta_key values does not change even after changing the wordpress table prefix:

  • wp_user_level
  • wp_capabilities
  • wp_autosave_draft_ids

I wrote an SQL statement to update meta_key values to:

  • wpkh_user_level
  • wpkh_capabilities
  • wpkh_autosave_draft_ids
UPDATE `wpkh_usermeta` SET `meta_key` = REPLACE( `meta_key` , 'wp_', 'wpkh_' );

Step 3:

In the options table, I had to change the ‘wp_user_roles’ into ‘wpkh_user_roles’ by following SQL query:

UPDATE `prefix_options` SET `option_name` = 'prefix_user_roles' WHERE `option_name` ='wp_user_roles' AND `blog_id` =0;

Done! I was able to access the admin panel successfully icon smile Wordpress error You do not have sufficient permissions to access this page.

Step 1: You can create MySQL table by following code:

CREATE TABLE `users` (  
    `oauth_uid` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,  
    `oauth_provider` VARCHAR(10),  
    `username` text,  
    `first_name` text,  
    `last_name` text,
    `email` text,
    `pic_square` text,
    PRIMARY KEY (`oauth_uid`)  
) ENGINE=MyISAM  DEFAULT CHARSET=latin1;

Step 2: Create Facebook session, Database Connect and Authentication

session_start();
 
if (!empty($_SESSION)) {
    header("Location: home.php");
}

mysql_connect('localhost', 'username', 'password');
mysql_select_db('dbname');

Step 3: Add Facebook library and create facebook application object

# require library
require("facebook.php");
 
# Creating the facebook object
$facebook = new Facebook(array(

            'cookie' => true
        ));

Step 4: get user id (getUser()) and user info (api->(‘/me’))

    # session active, get user id (getUser()) and user info (api->('/me'))
    try {
        $uid = $facebook->getUser();
        $fb_access_token=$session['access_token'];

Step 4: Check if the user is already registered

47
48
49

 
$query = mysql_query("SELECT * FROM users WHERE oauth_provider = 'facebook' AND oauth_uid = " . $user['id']);
        $result = mysql_fetch_array($query);

Step 5: If user has not registered already, add user information to mysql database

53
54
55
56
57
58

 
        if (empty($result)) {
            $query = mysql_query("INSERT INTO users (oauth_provider, oauth_uid, username, first_name, last_name, email, pic_square) VALUES ('facebook', {$user['id']}, '{$user['name']}', '{$user['first_name']}', '{$user['last_name']}','{$user['email']}', '".$photolink."')");

            $result = mysql_fetch_array($query);
        }

Step 6: Stores Varialbles in the Session

60
61
62
63
64

 
 $_SESSION['id'] = $result['id'];
        $_SESSION['oauth_uid'] = $result['oauth_uid'];
        $_SESSION['oauth_provider'] = $result['oauth_provider'];
        $_SESSION['username'] = $result['username'];

Step 7: Publish to facebook Wall if user permission is accepted
