How to Find Installed Extensions in Joomla
Use Joomla’s Central Extension List
Joomla maintains a central list of registered extensions. This is the best starting point for confirming whether a component, module, plugin, template, language, library, package, or other extension is installed—even when it does not create an obvious Administrator menu item.
Open the Extensions List
- Sign in to the Joomla Administrator.
- Go to System → Manage → Extensions.
- Enter part of the extension or vendor name in the search field.
- Use the available filters to narrow results by type, status, location, or plugin folder when needed.
Clear old filters if an expected extension does not appear.
Identify the Correct Extension Records
Check the extension name and type rather than relying only on a product brand. One product can install a package plus a component, modules, plugins, libraries, or templates. Site and Administrator locations can also distinguish similarly named entries.
Check Whether the Extension Is Active
Installed and active are not always the same thing. A plugin can be disabled, a module can be unpublished or have no menu assignment, and a template can be installed without being the active default style. Use the management screen appropriate to the extension type to confirm its operational state.
Find Extensions That Were Copied Manually
If compatible extension files were manually placed in Joomla’s standard extension directories but never installed, they may not appear in the normal installed list. System → Install → Discover can scan for supported discoverable extensions and register them through Joomla’s installer workflow. Do not use Discover merely because a normal installed extension is hard to find.
Use the List Before Maintenance
Before updating, disabling, or uninstalling a product, identify all related extension records and understand which ones belong together. Package-managed products can contain several constituent extensions; removing one piece independently can break the product or complicate later updates.
Verify What You Found
Compare the displayed extension information with the developer’s documentation and the version you intended to install. If the expected record is missing after an installer reported success, clear search filters, check for related package names, review the installation message/logs, and avoid manually creating extension database records.
