Dashboard Ojs3 Error

I’m using ojs version 3.3.0.5, 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

readfile($cachedFile);
Becomes
echo file_get_contents($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.

Hi @Sabda_Maulana

Have you tried to upgrade your installation to the latest 3.3.0-x ?
Some issues have been fixed from your current version to the latest one.

Best,
