Hi there,

I have downloaded the template I created. I tried to install it, but the Joomla (4) give an error : Internal Server Error.

I downloaded it again and tried not to use the Drag&Drop method. After that there was an installation falure again.

It sais: Call to undefined method Joomla\CMS\Installer\Adapter\TemplateAdapter::get()

Has anybody any idea what to do?

We are still waiting for the release of Virtuemart stable version. In the meantime, you can explore the new features of Joomla 4 and create a new Child Template based on default template Cassiopiea. All files are free to download.

Same error for me. No 3rd party extensions involved. I just wanted to test a simple edit of the blank template. Receive '0 Call to undefined method Joomla\CMS\Installer\Adapter\TemplateAdapter::get()'
