Hi!
Happy birthday!
I want to install the "visualin"-package (joomla 4) but after the installation I get the error:
"Class Joomla\Plugin\Installer\Package\Extension\PackageInstaller not found"
Indeed, when I take a look into your zip-file, this path does not exist.
When I ignore this message by "Continue" the installation seems to be ready, the config-file is created but the "installation" folder is still there.
After I deleted the "installation" folder manually, I get "error 500".
What to do?
Where to get a COMPLETE installation-zipfile?
Thanks!
