After installing a new theme, I get a blank page or a "500 Server Error" page
Usually it should not depend on our themes but on some modules and/or overrides coming with the previously used theme.

It's a good starting point to enable the "Debug mode" so:

1. Navigate to Advanced Parameters > Performance section in your PrestaShop admin panel
2. In "Debug Mode" section, set the Debug mode option to Yes and click "Save"
3. Navigate to a frontend/backend page you had issues on, press F5 to refresh the page and see the error(s) that occur.
