Known Causes

4 known causes

⚠️

Insufficient User Privileges

The MySQL user does not have the required GRANT privileges (e.g., SELECT, INSERT, UPDATE) for the specific table or database.

⚠️

Incorrect User or Host

The application or client is connecting with a user account or from a host that lacks the necessary permissions, or a different user is active than intended.

⚠️

Privilege Cache Not Refreshed

Recent changes to user privileges might not have been reloaded by the MySQL server, causing old permissions to remain enforced.

⚠️

Overridden Table-Level Permissions

Despite broader database or global privileges, specific table-level DENY or more restrictive GRANT statements can override them.
