A Guide to Troubleshooting Database Error.
Incorrect Database Credentials
- The database host, username, password, or database name in the wp-config.php file might be incorrect.
Database Server Issue
- The server hosting the database may be down or experiencing high traffic, preventing WordPress from connecting.
Corrupted Database
- Database tables can become corrupted due to plugin conflicts, server crashes, or interrupted updates, causing connection errors.
Insufficient Database User Privileges
- The database user may not have the required permissions to access or modify the database tables.
Exceeded Database Storage Limits
- Hosting providers often impose limits on database size. If these limits are exceeded, it can disrupt the connection.
Incorrect Table Prefix
- If the table prefix in the
wp-config.php
file doesn’t match the prefix in the database, WordPress cannot establish a connection.
