13.7. Updating a Theme
- A contributed theme has been installed and there is an update available for it. See Sección 11.5, “Downloading and Installing a Theme from Drupal.org” and Sección 13.4, “Keeping Track of Updates”.
- If your site is live, you should test this process in a development environment before running it on your production site. See Sección 11.8, “Making a Development Site”.
- You have created a full site backup. See Sección 12.3, “Concept: Data Backups”.
- If you want to use the user interface, the core Update Manager module must be installed. See Sección 4.3, “Installing a Module” for instructions on installing core modules.
You can use the administrative interface to update a contributed theme. If you are updating a custom theme rather than a contributed theme, if you see a message saying Installing modules and themes requires FTP access to your server, or if the steps below do not work to obtain the new theme files, follow the steps in Sección 11.6, “Manually Downloading Module or Theme Files”, and then continue with step 6 in the instructions for administrative interface below.
If you are using Composer to manage the files in your site, follow the steps in Sección 3.5, “Using Composer to Download and Update Files” to update the files, then continue here with step 6 in the instructions for the administrative interface below.
- Put your site in maintenance mode. See Sección 11.2, “Enabling and Disabling Maintenance Mode”.
- In the Manage administrative menu, navigate to Reports > Available updates > Update (admin/reports/updates/update).
Find and check the theme in the list. Click Download these updates for the theme.
- Click Continue.
- Click Run database updates. If you obtained the new theme files manually, start with this step, and reach the database updates page by typing the URL example.com/update.php in your browser.
- Click Continue to run the updates. The database update scripts will be executed.
- Click Administration pages to return to the administration section of your site.
- Take your site out of maintenance mode. See Sección 11.2, “Enabling and Disabling Maintenance Mode”.
- Clear the Drupal cache (refer to Sección 12.2, “Clearing the Cache”).
- Review the site log, see Sección 12.4, “Concept: Log”, once the updates are complete to check for errors.
