I have always love WordPress CMS, right from the very first i decided to use for blogging. My love for WordPress was threatened when i woke up one morning, i decided to check my blog, i was shocked when i saw Error establishing a database connection. If you experiencing this problem, then this piece will guide you on how to solve this error.
Causes & Solution To WordPress “Error establishing a database connection”
Below are some possible causes of this error and how to fix them.
- Database Settings in Wp-config.php file
If you are experiencing database error, the first thing you need to do is, navigate to wp-config.php file located at the root of your WordPress install folder and check if your MySQL Database settings are correct.
The MySQL code snippet is as below:-
// ** MySQL settings - You can get this info from your web host ** // /** The name of the database for WordPress */ define('DB_NAME', 'your database name here'); /** MySQL database username */ define('DB_USER', ' database username here'); /** MySQL database password */ define('DB_PASSWORD', ' yourpasswordhere'); /** MySQL hostname */ define('DB_HOST', ' localhost');
NOTE: Text inside /* */ are
comments, for information purposes only. Also, at define(‘DB_HOST’, ‘ localhost’);, there is a good chance you will NOT have to change it. If you are unsure, try installing with the default value of ‘localhost’ and see if it works. If the install fails, contact your web hosting provider.
- Mysql Database Broken
Having broken database or sometimes a database table can lead to inability for WordPress to connect to database. In my ordeal, this was actually the cause.
You can fix this problem with or without logging into PhpMyadmin.
Solving This Problem Without PhpMyAdmin – To do this, add
Once you have done that, you can see the settings by visiting this page: http://www.yoursite.com/wp-admin/maint/repair.php
Please note that The user does not need to be logged in to access this functionality when this define is set. This is because its main intent is to repair a corrupted database, Users can often not login when the database is corrupt.
With the above done, your database would have been repaired and your site up and running.
But in my case, the repair was unsuccessful, but i was happy the process told me the database table that was corrupted, so i had to repair the table via PhpMyAdmin.
Using PhpMyAdmin – You may decide to do a PhpMyAdmin Database test to detect the problem. to perform this test: Login to cPanel and click MySQL Databases, check all the tales, look for the drop-down called “Check DB”.
This should reveal the cause of the problem.
To Repair the detected database table, Go back to MySQL Databases -> Tick the corrupt table -> Scroll bottom, look for the drop-down called “Repair DB”, Select the database table which is having trouble, Click the Repair DB button.
Once complete, reload your website.
To prevent future occurrence of this problem, install WP-DBmanager. This plugin has an option for you to schedule how frequent your database will be optimised and repair, also it backup and mail you your database file as well as an option to drop/empty a table and run SQL queries without having to use phpMyAdmin. it a must have plugin.
With the above instruction adhered to, you must have successfully recovered your WordPress blog.
