error after installing a template

Post by Gany » Sat Apr 20, 2019 2:39 am

I tried the latest version. Anything I try to install crashes it. Error message:

An error has occurred.

0 Call to undefined method Joomla\CMS\Application\AdministratorApplication::isAdmin()

Hi, In Joomla! 4, there should be not more included this function:

Code: Select all

public function isAdmin()
		return $this->isClient('administrator');
So try to enable debug mode to see in which file and on which line you get the problem and try to replace from:

Code: Select all


Code: Select all

- Phoca Gallery - powerful image gallery -
- Phoca Restaurant Menu -
- Phoca Cart - e-commerce platform for Joomla!
- Phoca Download - download manager for Joomla!
