MySQL Common Issues

WordPress needs a working database connection to load content and settings. A connection problem may display Error establishing a database connection, a hosting database error or a general server error.

Common causes

• The database service is unavailable or the hosting account has reached a resource limit.
• The database name, username, password or host in wp-config.php is incorrect.
• The database user no longer has access to the required database.
• The server or hosting account has run out of storage.
• A table is damaged or an import or restore did not complete correctly.

What to check

1. Save the exact message and note whether it affects the whole site or one action.
2. Check the hosting status and account storage before changing WordPress.
3. Compare the connection details in wp-config.php with the database shown by the host.
4. Review recent migrations, password changes, imports or restores that may explain the timing.
5. If the host reports table damage, create a backup before using its recommended recovery process.

Get help with the error

A database error can have several causes with the same visible message. If you need a developer to investigate, submit a Fix Request and include the error wording and when it began. Add hosting access to the Password Vault if requested.
