Joomla compatibility
The current installed-agent release is 3.0.0-r22, dated 30 September 2026. It supports Joomla 5.4.8+ within 5.4.x and 6.1.3+ within 6.1.x, with PHP 8.3–8.5 and MariaDB 10.4+ through Joomla MySQLi or MySQL (PDO). InnoDB and the database user's TRIGGER permission are required. Ask your host to confirm these requirements before installing.
MySQL, PostgreSQL, other Joomla families, PHP below 8.3 and PHP 8.6 or newer are not supported by this release. Joomla's own requirements are separate from Flowpane's package requirements.
Tested combinations
The package carries forward the following recorded compatibility cells from 3.0.0-r16. These are local compatibility results, not a new full matrix rerun against r22 or certification of every hosting environment.
| Joomla | PHP | Database | Driver |
|---|---|---|---|
| 5.4.8 | 8.3.33 | MariaDB 11.4.5 | mysqli |
| 5.4.8 | 8.4.25 | MariaDB 11.4.5 | mysqli |
| 5.4.8 | 8.5.10 | MariaDB 11.4.5 | mysqli |
| 6.1.3 | 8.3.33 | MariaDB 11.4.5 | mysqli |
| 6.1.3 | 8.4.25 | MariaDB 11.4.5 | mysqli |
| 6.1.3 | 8.5.10 | MariaDB 11.4.5 | mysqli |
| 6.1.3 | 8.4.25 | MariaDB 10.4.34 | mysqli |
| 6.1.3 | 8.4.25 | MariaDB 10.5.29 | mysqli |
| 6.1.3 | 8.4.25 | MariaDB 10.6.28 | mysqli |
| 6.1.3 | 8.4.25 | MariaDB 10.5.29 | mysql (PDO) |
A tested cell is the complete Joomla/PHP/database/driver combination. Do not combine separate cells. Later patch releases inside the supported families may be accepted but have not been individually tested. Other combinations and hosting configurations remain unverified.
Reading environment compatibility
The Site Integrations panel shows reported Joomla, PHP, installed-agent, database and controller versions where evidence is available. Refresh status after an upgrade. Missing versions and combinations outside the panel's dated catalogue remain unverified; a current package support range does not silently update an older catalogue.
Only the database engine and version are shown as environment compatibility information. Flowpane does not upgrade Joomla, PHP, the database or SEO extensions. Compatibility information does not change governance scores or grant permission to manage a website.
SEO extensions
The installed-agent matrix does not certify OSMap or RSSeo versions. Check the environment and evidence date shown for each extension. Recognition alone does not make an extension supported or its output manageable.
RSSeo: monitor physical output
RSSeo output can be observed without granting Flowpane authority to change it. See What can be managed.
