Understanding the “WordPress Could Not Insert Attachment Into the Database” error
The error “WordPress could not insert attachment into the database” is not a bug in your theme or a failed plugin. It is, at its root, a database-level issue. WordPress relies on MySQL to store and manage content. When you upload an image, WordPress doesn’t just store it on your server; it also inserts a record of that image into the databases wp_posts and wp_postmeta tables, so that it can be retrieved and displayed on your website.
However, if something goes wrong during this process, you’ll see the “WordPress Could Not Insert Attachment Into the Database” error. The reasons can vary; let’s discuss them one by one.
Causes of the Error
Several things can cause this error to occur. But before diving into the backend, be sure this is the actual error. Upload a file in Media > Add New. If you see:
“WordPress could not insert attachment into the database.”
Then you’re likely facing one of the common database-level issues. You can also check your error_log or enable WP_DEBUG mode by adding this to your wp-config.php file:
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
This will write errors to /wp-content/debug.log helping you identify exactly where the issue is happening.
Now, let’s see some of the most common causes:

If your WordPress site’s database user doesn’t have sufficient permissions, it may not be able to insert data into the database, resulting in this error.
2. Database Corruption
If your database is corrupted or damaged, WordPress may not be able to insert data into it, leading to the error.
3. Plugin or Theme Conflict
In some cases, a plugin or theme on your WordPress site may conflict with the media upload process, resulting in an error.
4. Lack of Server Space
If your server doesn’t have enough space to store the uploaded media files, WordPress may not be able to insert them into the database.
