No dashboard on new linux hosting

As title, the dashboard module is in module directory (I use the modules from this topic Emoncms v11.2.3 stable release) but I can’t add a new dashboard, when I push “new” nothing appened…

I’m not sure what’s going on, but some ways to start finding out:

Anything in the error.log? If you open the browser developer tools, in the network tab, can you see a request being sent when you click new, and the server response? Any errors in the javascript tab?
