Error: The database is corrupted

The error appears when WordPress is unable to read or write the database correctly. It signals that the MySQL or MariaDB tables are damaged, the connection details are wrong, or a process interrupted a query.

When the database is corrupted WordPress stops loading core data. The result is a blank screen, an error message in the admin area, or missing content on the site.

Symptoms

Common Causes

Incorrect DB credentials
DB name, user, password or host in wp-config.php does not match the server
Corrupted tables
MyISAM or InnoDB tables become damaged after power loss or crash
Failed update
Core or plugin update stops mid‑process leaving incomplete SQL
Plugin or theme conflict
A plugin or theme runs bad queries or drops tables during activation
Low PHP memory
Memory limit aborts long DB operations leaving half‑written tables
