"'Faça sempre backup de seu site antes de atualizar."'

A forma recomendada para atualizar instalações do Joomla! é o componente Joomla Updater, localizado no menu Componentes do Painel de Controle.

Atualizar de versões anteriores? Você deve usar o Install Method.

Você deve sempre verificar os artigos Upgrading Issues e Known upgrading issues and solutions antes de atualizar.

Acesse Componentes, Joomla! Update

Se houver uma atualização disponível, você encontrará uma mensagem indicando isso e um botão para clicar. A atualização que você verá depende das configurações de servidor de atualização e caching do componente. Veja Opções para o componente Atualização Joomla!. A primeira opção mostra a atualização mais recente da versão que está em uso. A segunda opção mostra a atualização mais recente da última versão do Joomla! disponível. O armazenamento em cache pode causar a não detecção de uma atualização disponível, então limpe o cache.


Click on the "Install the Update" Button and Allow the Update to Run


When it has completed you may need to refresh your screen or empty your browser cache to adjust for template CSS changes.

Note: Joomla! will notify you on your Administrator home page (control panel) when an update is needed, but it will not do the update for you. You need to press the button to start the update.

Recommended Steps and actions: It is recommended that you follow these steps when updating a production site:

  1. Back up your site before upgrading to a new version. That way, if something goes wrong during the upgrade process, you can easily restore your site to the earlier version.
  2. Review the release notes for the new version to be familiar with what was changed.
  3. Update using one of the recommended methods outlined in this document. These methods install the new program files, delete unneeded old program files, and update the database as needed for the new Joomla version.
  4. Clear your browser cache and check that the update was successful, using the steps outlined in the Checking Site tab.

Checking Your Site

After an update, it is a good idea to clear your browser cache and check your site to make sure the update was successful. There are two quick checks you can do from the Extension Manager.

Extension Manager: Check Database

Joomla 2.5 This feature was added in version 2.5.0. It checks that your database is up to date with your Joomla! programs.

Navigate to Extension Manager  Database. If your database is up to date, you should see a screen similar to the one below:

Database Screen With No Problems

If your database is not up to date, you will see a screen listing the problems found, similar to the one below:

Database Screen With 3 Database Problems

In this case, press the Fix button in the upper right corner. Joomla will update your database to correct the issues listed and then it will re-display the screen. If the fix was successful, the display will indicate that the database is up to date.

N.B. If any errors still exist make sure all the database tables are checked in.

Extension Manager: Discover

In some cases, when you update to a new Joomla version, new core extensions are added. If there were problems with the database update, these extensions may not have been correctly installed. To check this, navigate to Extension Manager  Discover. Then click on the Discover icon in the toolbar. The screen should show as follows:

Discover Screen With No Extensions To Install

If so, you know that any new extensions added during the update were correctly installed in the database.

If there are uninstalled extensions, they will show similar to the following screen:

Discover Screen With One Extension To Install

In this case, check the boxes and click on the Install icon in the toolbar. Joomla will install the extension(s) and then display the screen showing no extensions discovered. At this point, the new extensions have been installed in the database.


If you have any questions before, during or after the upgrade, please ask them on the Migrating and Upgrading to Joomla! 3.x Forum.

If you have problems or errors during the update process, here are some tips.

  • Check the following locations for more information:
  • Clearing your browser cache. There may have been changes to the CSS or Javascript that will need to be reloaded by your Web browser after an upgrade.
  • If any database error messages show after the update, be sure to check the Extension Manager: Database tab followed by the Extension Manager: Discover tab. In some cases, if a database error occurs it will prevent all the database updates from running. In this case, you can run them from the Database tab and then use the Discover→Install method to check and install any new extensions.
  • If you encounter any errors or problems during or after the update, be sure to check the FAQ for the version you updated to. For example, for version 3.1.0, this will be an category entitled Category:Version 3.1.0 FAQ.
