which app did you install?

[satriani-vai]

Just all the apps inside the MuK Documents here: https://apps.odoo.com/apps/modules/11.0/muk_dms/
This error occurs when muk_web_client_refresh is in the Addons folder.

[keshrath]

inside the __init__.py change import models to from . import models

Same for muk_web_preview_attachment
