Database Query Error
A plugin or theme is sending an incorrect query to the database. This is usually caused by outdated plugins or custom code.
Why this happens
A plugin or theme is sending a malformed query directly to your database - often because it wasn't updated for a newer version of WordPress or MySQL/MariaDB, or because custom code contains a mistake in raw SQL. Since this touches your actual data, it's one of the more delicate errors to fix.
Step-by-step fix
- Check the error message for which query or plugin is mentioned.
- Update that plugin - if no update is available, disable it temporarily.
- Back up your database first (this step is very important).
- If you can't fix it yourself, get help from a database expert or developer - mishandling the database can corrupt your site's data.
How to prevent it happening again
- Avoid writing raw SQL queries in custom code unless necessary - use WordPress's built-in $wpdb methods, which handle compatibility for you.
- Keep plugins that interact directly with the database (like custom fields or e-commerce plugins) updated.
- Always take a full database backup before attempting any manual database fix.
