Duplicate usernames cause update issue/es: Difference between revisions

Revision as of 17:15, 10 March 2020

En ciertos sitios web, actualizar a Joomla 3.9.16 provoca un error en la base de datos debido a nombres de usuarios duplicados. Si eso pasa, no entrar en pánico - la actualización ha sido mayormente completada sin problemas, y el cambio restante de la base de datos puede realizarse después de seguir las instrucciones que figuran a continuación.

Errores reportados

Los usuarios reciben un error de actualización en relación con una consulta fallida de la base de datos debido a una clave duplicada en una tabla de su sitio web #__users al actualizar a Joomla 3.9.15 o posterior.

Información General

What is the cause

Your website has more than one user in the #__users table with the same username, which is a security concern in that the incorrect account may be accessed by the wrong account owner.

How to fix

You will need to review your #__users table in your database and fix any duplicated usernames by either removing old user accounts or changing the username until all usernames are unique. Once this is finished, if you have already upgraded to 3.9.16 run the database schema fixer tool to finish the upgrade (this step is not required if you do this review prior to upgrading).

Joomla is unable to automatically determine the correct action to take and as a result is unable to perform this step for you - it has to be fixed by you as the site owner.

The following SQL Query can be run on your database to view which usernames are duplicated:

SELECT username FROM #__users GROUP BY username HAVING COUNT(*) > 1
