I installed Joomla 3.9.6. When trying to install Portal extension 2.0.1 I got this message:
JInstaller: :Install: Can’t find XML setup file.
Joomla\CMS\Filesystem\Folder::create: Could not create folder.Path: /var/www/html/portal/administrator/components/com_advancedopenportal
Component Update: Failed to create folder: /var/www/html/portal/components/com_advancedopenportal.
Looks like there is version issue? If that is the issue, what is recommended Joomla version?
