Dashboard Ojs3 Error

I’m using ojs version, when I open the dashboard menu it looks like this, like the css file inside is unreadable.

I’ve tried replacing Make changes in /lib/pkp/controllers/page/PageHandler.in.php

echo file_get_contents($cachedFile);

And it still doesn’t work either.

And I’ve also deleted the cache files and templates in the administrator menu and it still doesn’t work.
