Hi Steve,

we didn't publish template/QS version for Joomla 4 yet. Updated SP Property and SP Page Builder components are fully compatible with Joomla 4. Helix3 framework v3.0.2 should work in J4 as well, but template itself may not.

Hi Paul, I'm having problems upgrading to J4 even though I disabled any potential problem components & plugins.

Now I can not get around this error message: Cannot access protected property Joomla\CMS\Menu\MenuItem::$params

Is there anyway of knowing if and when Empire will become Joomla 4 compatible?

Cheers Steve

It can be from template helix plugin or administrator module or ???. Sorry but Joomla upgrade is beyond support. Ask uncle Google and turn on showing errors to maximum in configuration.php file.

I hope in next few weeks.

Hi Paul, the problem is the Joomshaper Empire template.

I know this because when I select the Cassiopeia Template (which comes with J4 install), I do not get the error.

Full error is below: error - Uncaught Throwable of type Error thrown with message "Cannot access protected property Joomla\CMS\Menu\MenuItem::$params". Stack trace: #0 [ROOT]/libraries/src/Document/HtmlDocument.php(779): require() #1 [ROOT]/libraries/src/Document/HtmlDocument.php(838): Joomla\CMS\Document\HtmlDocument->_loadTemplate('/home/customer/...', 'index.php') #2 [ROOT]/libraries/src/Document/HtmlDocument.php(641): Joomla\CMS\Document\HtmlDocument->_fetchTemplate(Array) #3 [ROOT]/libraries/src/Application/CMSApplication.php(1025): Joomla\CMS\Document\HtmlDocument->parse(Array) #4 [ROOT]/libraries/src/Application/SiteApplication.php(802): Joomla\CMS\Application\CMSApplication->render() #5 [ROOT]/libraries/src/Application/CMSApplication.php(284): Joomla\CMS\Application\SiteApplication->render() #6 [ROOT]/includes/app.php(63): Joomla\CMS\Application\CMSApplication->execute() #7 [ROOT]/index.php(32): require_once('/home/customer/...') #8 {main}

Is there anyway of knowing if and when the Empire Template will become Joomla 4 compatible?

Thanks Steve
