Updating Joomla 4
Joomla 4.3.3 is now the latest release of the popular open-source content management system (CMS) that powers millions of websites around the world. With its advanced features and enhanced security, it is important to keep Joomla up-to-date to ensure the best user experience and prevent potential security vulnerabilities.
Here is a comprehensive guide on updating Joomla 4 to the latest version, covering everything from preparing for the update, methods of updating, common issues and troubleshooting, and verifying the update was successful.
TL:DR Joomla updates can get messy. To avoid problems you should back up your website to ensure that you can restore it in case of an issue. Then before you update you should check that your web service providers system meets the system requirements for the update, and that all extensions and templates you use are updated to the latest version, as older versions of these may not be compatible with the latest Joomla release. Once you have done that a Joomla update should be a painless experience!

Joomla 4 is a powerful CMS that provides users with enhanced features such as improved accessibility, a revamped media manager, and a more intuitive user interface than its predecessors. These features are designed to improve the user experience, streamline the content management process, and provide Joomla users with greater control over their website.
The importance of keeping Joomla up-to-date
Updating Joomla is important for several reasons.
- Firstly, it ensures that your website is running on the latest version of the CMS, which can improve performance, security, and provide improved functionality.

Joomla 4 step-by-step update
Step 1 – Backing up Joomla 4
In order to prepare for the update, you should start by backing up your Joomla website. This step is crucial because it ensures that you have a copy of your website in case anything goes wrong during the update process. You can use a backup extension for example Akeeba Backup or manually create a backup of your website files and database. It's recommended that you store the backup files in a different location to your Joomla site, such as a cloud storage service or an external hard drive.
Step 2 – Checking Joomla 4 required and recommended settings
Before updating Joomla, it is essential to check that the update is compatible with your hosting providers system requirements. These requirements include PHP version, database version, and server settings. It is unlikely but possible that a Joomla 4 update could require you to adjust these settings using your hosting providers control panel tools. It is more likely that this would be required for a major version upgrade rather than an update. You should use the Pre-Update check provided by Joomla 4 as part of the update process to do this.

Recommended Settings
These settings are recommended for PHP in order to ensure full compatibility with Joomla. However, Joomla! will still operate if your settings do not quite match the recommended configuration.

Step 3 – Checking Joomla 4 extensions and templates
Ensure that all extensions and templates are updated to the latest version, as older versions may not be compatible with the latest Joomla version. Review the extensions page of the pre-update check and consider checking with the developers of your extensions and templates if it is unclear that they are compatible with the latest version of Joomla. If they are not compatible, you may need to find alternative extensions or templates to use with Joomla 4, and your update may fail.
Extensions
You may see 'Update Information Unavailable' if Joomla cannot detect the extension's compatibility with the target version of Joomla.

Step 4 – Verifying the site is ready for the update
Before updating Joomla, it is essential to verify that your site is ready for the update. You can rely upon the pre update check which is part of the update process but you may also choose to try out the update on a restored backup of your site before deploying it in production.
Step 5 – Updating Joomla 4 using the Joomla Update Component.
To update Joomla 4, follow these steps:
- Log in to the Joomla administrator site.
- Click System. This will take you to the System Dashboard.
- Click the Joomla link under 'Updates' and you will be taken to the Update Component.
- Carry out the pre-update check and remedy any issues before continuing. You have to acknowledge the warnings about potentially incompatible extensions to proceed with the update.
- Acknowledge that you should take a backup by selecting the checkbox and then click 'Start Update'

Common issues and troubleshooting
Common issues that occur during updates include compatibility issues with extensions and templates, PHP errors, and database errors. Troubleshooting techniques for resolving these issues include disabling extensions and templates, increasing PHP memory limits, and checking database connection settings. Best practices for preventing issues during updates include keeping your extensions and templates up-to-date before you update, testing updates on a staging site before applying them to your live website, and creating regular website backups.
Verifying your Joomla 4 site updated
After the update, it's important to verify that the update was successful. This can be done by checking the version number in the Joomla administration area and ensuring that all website functionality is working properly. If any issues arise after the update, they should be addressed immediately to avoid any negative impact on website visitors or search engine rankings.
