Hola Soy nuevo en esto del ojs y me estoy perdiendo un poco, bueno bastante para ser sinceros

Hasta ahora tengo este problema DB Error: Unknown column ‘gender’ in ‘field list’, busque en el mysql y la tabla no la veo o no existe.
Si pudieran ayudarme se los agradeceria.

This means that your source code is at a different version than your database. Did you recently try an upgrade? If you updated the source code, but either did not run the upgrade.php script, or if you ran the upgrade.php script but it did not complete successfully, your database may be out of sync with the source code.

To resolve this, run the upgrade.php script, or restore the backup from prior to the upgrade and try the upgrade again.
