Seeing the WordPress error establishing a database connection means your website cannot communicate with its database. This can happen because of incorrect database credentials, a MySQL service issue, corrupted database tables, insufficient database permissions or a hosting configuration change. I investigate the actual cause instead of applying random fixes.
I start by reviewing your WordPress configuration, including the database name, username, password and database host in wp-config.php. I then check database connectivity, MySQL availability, user permissions and relevant server error logs. If the issue involves corrupted tables, I inspect their condition and apply an appropriate repair where possible.
Once I identify the cause, I make the necessary configuration or database corrections and test the website again. I check both the public website and WordPress admin area to confirm that they can communicate with the database. I also explain what caused the problem and what I changed.
This is a focused troubleshooting service for an existing WordPress website. It covers one database connection issue and the fixes directly related to it. It does not include hosting migration, major database restructuring, malware removal, website redesign or unrelated development work. If the problem requires hosting-provider intervention or additional work outside this scope, I explain the findings and discuss the next steps before proceeding. I work remotely with clients worldwide from Lahore, Pakistan.
