I set the pruebas theme for testing and i have some errors...

Hi there, i set the pruebas theme, for learning all the process with the builder and for now i see some errors...

First, when i tried to save the theme, the upfront builder didn't save the /library/ directory, and when i tried with the editing mode, the teme is broke down.

Once the /library/ directory is copied in the correct path, the upfront have the Fatal error: Uncaught Error: Class 'Upfront_Permissions' not found in
