Hi,

I just updated our [Discourse Forum](https://forum.humancoders.com/) and it’s now blank (homepage and admin). The HTML looks OK, RSS are working.

I found JS errors due to our theme. Can the problem come from here?

How can I fix that? Can I modify/disable the JS code of my theme from CLI? Install a new theme?

Edit: I’ve no other theme installed, so i can’t use `?preview_theme_id=`
