Beaver stopped working except on front page

Can you please help? I’m not sure what happened. We’ve been moving our site lately to another server and everything seemed to work at first.

I’m not sure what exactly went wrong as this happened a little while after the site was moved so I’m not sure it’s related. But suddenly the beaver plugin will only work on the front page.
It will not work on any other page. it shows the “page builder” button on all page in the admin-bar, but when I click it, nothing happen. Well, the “thinking” indicator does indicate that its thinking for a second, but otherwise no reaction. The beaver plugin never loads. It doesn’t work if I just make a new page either.
Only the static front page works.

What could possibly cause this? I am almost certain it’s not the plugin’s fault, because we have a copy-site somewhere with the exact same plugins where it works.
