WordPress Database Error Malformed packet for query

You are in luck if you are stuck with the “malformed packet for query” error in WordPress. Our experts have helped out several of our customers with the very same issue recently.

This error pops up when there is an issue with the data being sent or received between the web server and the MySQL database. In other words, the MySQL server received a packet but could not process it correctly.

Troubleshooting Tips

Our experts have put together these steps to help you troubleshoot and fix the “malformed packet for query” error in WordPress:

• The first step is to check the MySQL server logs for more information about the error. This will give us a better insight into the error.
• Next, we have to ensure that we are using compatible versions of PHP and MySQL.
• Then, it is time to check the WordPress site’s database connection settings in the wp-config.php file. We have to verify that the database host, username, password, and database name are correct.
• If the above tips did not help, we have to create a PHP script to test the database connection outside of WordPress. This will help us find out if the issue is specific to WordPress or a more general database problem.
• Alternatively, we can deactivate all plugins and switch to a default theme and then check if the error persists. If it goes away, we can reactivate plugins and the theme one by one to identify the one causing the issue.
• Sometimes the error is due to a large amount of data being transmitted. In this case, we can increase the MySQL packet size in the MySQL server configuration.
• Furthermore, we can use MySQL tools to verify and repair the integrity of the WordPress database.
• Next, we have to verify that there are no network or firewall settings preventing communication between the web server and the database server.
