All our Joomla! extensions are ready for Joomla! 5 (except for GeoTax for J2Store). Please note:
- It is important to update our extensions before updating Joomla! itself.
- The B/C Plugin ("Behaviour - Backward Compatibility") must be enabled.
What does "Joomla! 5 (B/C Plugin)" mean?
In the Joomla! extensions directory you will find compatibility for Joomla! 5 and Joomla 5 (B/C Plugin). What does that mean?

The B/C plugin is already installed and activated in your Joomla! 5 installation. It enables "backward compatibilty" for code that was already used in Joomla! 3 and 4. Without the plugin, legacy methods are no longer available and plugins that use them do no longer work.

Newly written or reworked extensions can have native Joomla! 5 compatibility. In most cases where you find an extension that is ready for multiple Joomla! versions, the B/C plugin will be needed.
Please be sure to use the latest versions of our extensions. Joomla! 5 support has been added to our extensions since the following versions:
Joomla Extension Aimy... | Version |
---|---|
Sitemap | ✓ 32.4 |
Speed Optimization | ✓ 19.6 |
Canonical | ✓ 27.0 |
IndexNow | ✓ 4.1 |
Video Embedder | ✓ 17.2 |
Responsive Iframes | ✓ 6.1 |

If you have any issues with our extensions while updating to Joomla! 5 feel free to contact us!
Why do our extensions need the backward compatibility plugin?
Short answer: because we don't want to drop support for Joomla! 3 right now as it is still used on thousands of websites.
