This MySQL error appears when a query or command tries to use a server option that has been disabled at compile-time or startup.
MySQL Error 55 EE_USING_DISABLED_OPTION occurs when a statement references a disabled server option. Re-enable the option with --enable-option_name at startup or remove the conflicting clause to resolve the issue.
%s: Option '%s' was used, but is disabled. EE_USING_DISABLED_OPTION was added in 8.0.13.
The server raises this global error when a statement accesses an option that MySQL was compiled without, or that the DBA explicitly disabled with a startup flag. Because the option is unavailable, the server blocks execution to prevent undefined behavior.
The message often surfaces after version upgrades, configuration migrations, or when copying sample commands from documentation that assume optional components are enabled.
It can also occur in containerized deployments where minimal builds are used.
Ignoring the error leaves functionality incomplete and can break automation scripts. Production outages may occur if startup halts due to an invalid option, so addressing the disablement ensures smoother deployments and predictable performance.
.
The error message prints the exact option name after the colon. Check your MySQL error log for details.
Most compile-time disabled options cannot be toggled dynamically. You must restart MySQL with the feature enabled or install a compatible build.
Upgrading retains your my.cnf. If the binary supports the option and the flag remains, it becomes active after the upgrade.
