Advertisement

WordPress definitely one of the most complex PHP-MySQL web application with too many vulnerabilities. Sudden WordPress wp-login Redirection to Homepage is Common Problem After Upgrade of Plugin, Installation of Plugin, SQL Injections & Other Compromises. One of the reason is full wrongful deletion of user role capabilities from MySQL table by the preceding reason. Here is How to Restore WordPress Admin User Role Capabilities.

 

WordPress wp-login Redirection to Homepage : Restore WordPress Admin User Role Capabilities

 

The topic is very complex, make sure that the wp-login redirection to homepage issue is out of deletion of user role capabilities. In that case, nothing easy solution will work, you will simply be able to login but redirected to homepage with your capabilities limited to viewing the WordPress bar exactly we view on regular basis after logged in, however you’ll not see any privileged options as dropdown menu – there will be no option to write new post.

After such massive disaster, expect more issues to solve. This problem is not difficult for those are used with sysadmin works as webmaster. You simply need root access to server to use the MySQL CLI for fast work. PHPMyAdmin definitely works but not exactly what we should use on single server setup (to reduce vulnerabilities).

Restore WordPress Admin User Role Capabilities

 

Login to MySQL CLI with usual command :

Vim
1
mysql -u root -p

Run the below command to check names of databases :

Vim
1
show databases;

Then go to the database which your WordPress installation under question uses :

Vim
1
use your-database-name-here;

Then run this query :

Vim
1
SELECT * FROM wp_options WHERE option_name='wp_user_roles';

The above will return very big result :

Vim

a:number is the beginning of array and the number count of array elements. WordPress has e5 roles.
s:number means string element. s:6 is author. b:number means Boolean element with value true or false.

We actually undergone a disaster and at this moment, we have 404 of all images and no custom sidebar things as remaining issues. It is worthless to restore backup blindly without checking the issue creating it. It is bad if you do not have backup of different times. The values remaining from that will indicate the offending plugin. Updating wpseo plugin deleted our 1500 stuffs of MySQL database, cleaned .htaccess file. Why, that is difficult to say. It may be used to run exploit by someone else or plugin coding had bugs which triggered by some other thing.

My one became this :

Vim
1
2
....
wp_user_roles | a:2:{s:13:"wpseo_manager";a:2:{s:4:"name";s:11:"SEO Manager";s:12:"capabilities";a:3:{s:15:"Capabilities_bulk_edit";b:1;s:28:"wpseo_edit_advanced_metadata";b:1;s:20:"wpseo_manage_options";b:1;}}s:12:"wpseo_editor";a:2:{s:4:"name";s:10:"SEO Editor";s:12:"capabilities";a:2:{s:15:"wpseo_bulk_edit";b:1;s:28:"wpseo_edit_advanced_metadata";b:1;}}}...

How you’ll login to WordPress admin with such? Your definition of power is lost.

It is actually not good to see it just few values there! That means the reason which deleted the values may have deleted, altered many other settings. Consider yourself lucky if your blog showing texts of posts. You can somehow restore images even if you have no backup (if you use Pinterest like social sites to share images) but loss of text of posts, categories can kill your many years effort.

How to add those stuffs to wp_options? Adding these to themes’s functions.php file for a while will restore them :

Vim
1
2
3
4
if ( !function_exists( 'populate_roles' ) ) {
require_once( ABSPATH . 'wp-admin/includes/schema.php' );
}
populate_roles();

There is a good gist around it :

Vim
1

In case, you are searching for SQL instead of the above fix, that will be like this :

Vim
1
2
UPDATE wp_1_options SET option_value='a:5:{s:13:"administrator";a:2:{s:4:"name";s:13:"Administrator";s:12:"capabilities";a:47:{s:13:"switch_themes";b:1;s:11:"edit_themes";b:1;s:16:"activate_plugins";b:1;s:12:"edit_plugins";b:1;s:10:"edit_users";b:1;s:10:"edit_files";b:1;s:14:"manage_options";b:1;s:17:"moderate_comments";b:1;s:17:"manage_categories";b:1;s:12:"manage_links";b:1;s:12:"upload_files";b:1;s:6:"import";b:1;s:10:"edit_posts";b:1;s:17:"edit_others_posts";b:1;s:20:"edit_published_posts";b:1;s:13:"publish_posts";b:1;s:10:"edit_pages";b:1;s:4:"read";b:1;s:8:"level_10";b:1;s:7:"level_9";b:1;s:7:"level_8";b:1;s:7:"level_7";b:1;s:7:"level_6";b:1;s:7:"level_5";b:1;s:7:"level_4";b:1;s:7:"level_3";b:1;s:7:"level_2";b:1;s:7:"level_1";b:1;s:7:"level_0";b:1;s:17:"edit_others_pages";b:1;s:20:"edit_published_pages";b:1;s:13:"publish_pages";b:1;s:12:"delete_pages";b:1;s:19:"delete_others_pages";b:1;s:22:"delete_published_pages";b:1;s:12:"delete_posts";b:1;s:19:"delete_others_posts";b:1;s:22:"delete_published_posts";b:1;s:20:"delete_private_posts";b:1;s:18:"edit_private_posts";b:1;s:18:"read_private_posts";b:1;s:20:"delete_private_pages";b:1;s:18:"edit_private_pages";b:1;s:18:"read_private_pages";b:1;s:12:"delete_users";b:1;s:12:"create_users";b:1;s:14:"edit_dashboard";b:1;}}s:6:"editor";a:2:{s:4:"name";s:6:"Editor";s:12:"capabilities";a:33:{s:17:"moderate_comments";b:1;s:17:"manage_categories";b:1;s:12:"manage_links";b:1;s:12:"upload_files";b:1;s:10:"edit_posts";b:1;s:17:"edit_others_posts";b:1;s:20:"edit_published_posts";b:1;s:13:"publish_posts";b:1;s:10:"edit_pages";b:1;s:4:"read";b:1;s:7:"level_7";b:1;s:7:"level_6";b:1;s:7:"level_5";b:1;s:7:"level_4";b:1;s:7:"level_3";b:1;s:7:"level_2";b:1;s:7:"level_1";b:1;s:7:"level_0";b:1;s:17:"edit_others_pages";b:1;s:20:"edit_published_pages";b:1;s:13:"publish_pages";b:1;s:12:"delete_pages";b:1;s:19:"delete_others_pages";b:1;s:22:"delete_published_pages";b:1;s:12:"delete_posts";b:1;s:19:"delete_others_posts";b:1;s:22:"delete_published_posts";b:1;s:20:"delete_private_posts";b:1;s:18:"edit_private_posts";b:1;s:18:"read_private_posts";b:1;s:20:"delete_private_pages";b:1;s:18:"edit_private_pages";b:1;s:18:"read_private_pages";b:1;}}s:6:"author";a:2:{s:4:"name";s:6:"Author";s:12:"capabilities";a:10:{s:12:"upload_files";b:1;s:10:"edit_posts";b:1;s:20:"edit_published_posts";b:1;s:13:"publish_posts";b:1;s:4:"read";b:1;s:7:"level_2";b:1;s:7:"level_1";b:1;s:7:"level_0";b:1;s:12:"delete_posts";b:1;s:22:"delete_published_posts";b:1;}}s:11:"contributor";a:2:{s:4:"name";s:11:"Contributor";s:12:"capabilities";a:6:{s:12:"upload_files";b:1;s:10:"edit_posts";b:1;s:4:"read";b:1;s:7:"level_1";b:1;s:7:"level_0";b:1;s:12:"delete_posts";b:1;}}s:10:"subscriber";a:2:{s:4:"name";s:10:"Subscriber";s:12:"capabilities";a:2:{s:4:"read";b:1;s:7:"level_0";b:1;}}}'
WHERE option_name='wp_1_user_roles' LIMIT 1

It is not odd to face no CSS, JS loading in WordPress backend. Possibly you’ll need to reset WordPress admin’s capabilities. In “wp_usermeta” table there will be “wp_capabilities” entry for the admin user (the user ID will allow you to verify). Default value is the following:

Vim
1
a:1:{s:13:"administrator";s:1:"1";}

I can understand you have not understood. Run the following :

Vim
1
2
3
4
5
# get user ID:
SELECT * FROM wp_users WHERE user_login='write_your_user_login';
# find what capabilities are assigned
# N is a value from the record ID field from first command's output
SELECT * FROM wp_usermeta WHERE user_id=N AND meta_key='wp_capabilities';

You’ll be able to login in proper manner. You’ll get useful detailed in-depth posts related to troubleshooting, fixing WordPress Admin User Roles :
