To resolve "Error when connecting to a database" in WordPress
Exactly what does this mistake mean? We' ll go through exactly what the error means and what it could cause in this paper, and then I'll guide you through some debugging and debugging that. Meaning "Error connecting to a database"? Let's first take a look at how WordPress works to view your website, and it will become clear why this error is so disastrous.
WordPress softwares are developed with PHP and MySQL. Since all the information that makes up your site is saved in a MySQL database, and WordPress uses PHP to save and recall information from that database. The PHP is used to connect to your MySQL database and get all the information needed to build the page.
There is one PHP request to get the mail header, another to get the name of the writer, another to get the release date, and so on. Return to your error message: "Incorrect database connection. "This means that for some sort of reasons the PHP source could not establish a connection to your MySQL database to get the information it needs to set up this page.
Therefore, this error is often all you see on an otherwise empty page. There is no way to know what to view if you cannot link to your database; there is no information available about your website. And what is causing this error? Whilst the significance of the error is clear, the causes of its appearance are often unclear.
While there are many possible causes why your website might have problems linking to your database, they generally come in three categories: You have entered incorrect data for your database. The database uses different logon information (username and password). When this credential is recently modified, your Web site can no longer use the old credentials in the database.
Their database is corrupt. A variety of things can damage your WordPress database, from the upload of a poor plug-in to flashes on the web site (seriously, though fortunately not too often). Your database host is down. Because of a web host issue or error, your database servers may be down, or you may experience a large amount of data spiking that your servers just couldn't withstand.
This is an indication that the database has been damaged. WorldPress has a built-in way to try to fix your database, but you need to activate this function first. This requires accessing your wp-config. php files, which contain your WordPress install setup and outline. Find wp-config in the folder of your WordPress home folder.
It can be accessed by connecting to your cPanel, choosing File Manager, and browsing to the directory where you install WordPress. As soon as you open wp-config, insert this line of source below: define('WP_ALLOW_REPAIR', true); this line allows you to optimise and fix your database by browsing to www.yourwebsite.com/wp-admin/maint/repair. phi (simply substitute "yourwebsite.com" with your current URL).
We recommend that you see the above display with two choices for either fixing or fixing and optimizing your database. Notice that this database recovery page is not safe; anyone can visit this site without logging in. As soon as you have finished fixing your database, be sure to delete the line of source that you added to wp-config.
As a result, accessing the repairs page is disabled and someone else is prevented from coming into contact with your database. For the time being, keep wp-config open until you are sure that the error has been fixed and your website is working again. You still get the same error messages, so you need to open wp-config for the next one.
Next, if the above did not work or does not work for you, you can take a look at your database preferences in your wp-config files. You wonder how your database logon data could suddenly no longer work? Items such as the change of host company or the change of database name or username can cause the error if your wp-config has not been upgraded to the new information.
It is possible that you have still opened the wp-config from the last stage. Otherwise, sign in to your host's cPanel and open the Files Manager. Browse to the folder where you have WordPress and search for a filename named a. o. php-files. You will see the logon information for your database, probably at the top of the screen.
WordPress should look like this: define('DB_NAME','database_name_here'); define('DB_USER','username_here'); define('DB_PASSWORD','password_here'); define('DB_HOST','localhost'); As you can see, there are four things WordPress needs to get your database: When any of these settings is wrong, WordPress cannot establish a connection to the database.
A way to verify your database outside WordPress is to use the PHPMyAdmin, a MySQL database access and manipulation utility. Take great care with PHPyAdmin as you are directly involved with the database of your website. After you have registered with the PHPMyAdmin, you will see a database on your computer in the menu on the right.
Clic on the one that corresponds to the name in your wp-config files (it will be the value after DB_NAME where the above example contains "database_name_here"). When you click on your database name, the system fills the home page with the name of the database files. In order to make sure it is the right database, find the "wp_options" spreadsheet and click the "Browse" button next to it.
You now know whether you have the right database name in your wp-config or not. When it is not correctly, fix it in the wp-config. We will now verify the login name and your login name. Simply generate a new account and passphrase and update your wp-config with the new information.
Policy 1: Test your available login information. In your WordPress folder, make a filename named testconnection. The name of the filename does not play a role (only the filename extensions . php). mysql_connect ('localhost','root','password'); the('Error:' . mysql_error()); the ' echo' database connection works! mysql_close ($testConnection); After creating this filename, simply browse to the filename in your web navigator (e.g. your site.com/testconnection.php).
You will see either a connection success or an error with further detail. In case the login and your passwort do not work, we can simply generate a new one. Policy 2: Creates a new database account and a new passphrase. You can do this with another available utility in cPanel named "MySQL® Databases".
a MySQL user: Insert a new user. "Select a user name and a secure passphrase and write them down for your wp-config in. Then click on " User creation ". "Browse down to the "Add user to database" headline, select your new user name and your WordPress database, and click "Add". "Refresh your wp-config with the new user name and passcode.
Your database name, user name and passphrase are now valid. WorldPress has a shared host listing with their DB_HOST readings on their website. Consult your web host company's technical department and give them all the error detail and corrective action you have taken, and they can help you identify the cause of the error.
