Hi:

Got this: Since joomla/database 2.2.0: The parameter $new is deprecated and will be removed in 5.0, use Joomla\Database\DatabaseDriver::createQuery() instead. - [ROOT]/librar....

As cjForum is the extension tested and trying to do a new Topic, maybe the error is related.  Anothe DB realted message was:

Joomla\CMS\Factory::getLanguage() is deprecated. Load the language from the dependency injection container or via Joomla\CMS\Factory::getApplication()->getLanguage()>
2025-10-26T21:04:19+00:00 WARNING xxxx deprecated Joomla\CMS\Factory::getDbo() is deprecated. Load the database from the dependency injection container. - [ROOT]/libraries/src/Factory.php - Line 453

Thanks.
