I created a theme on Magento 2 1.0.0beta. Now I updated to Magento 2.0.0 RC. After this update, my theme does not show up anymore on the Content > Themes page.
What I did to update my theme
- I changed the xsd scheme from lib internal to urn:magento:framework:
- I added registration.php
I also tried to add my theme directly to the theme database table. After this my theme does show up. But when I activate the theme I get this error:
Required parameter 'theme_dir' was not passed
Do I have to do something additional to make my theme work? Or do I need to activate it somehow?
