Hi Amir, as per your suggestion, I checked the chrome network tab and discovered this:

Not Found The requested URL /apps/studio/v2.0.2/templates/.html was not found on this server.

I ran the following to try to resolve the error but still getting the same No Found error.

yum clean all

yum update kaltura-html5-studio

/opt/kaltura/bin/kaltura-config-all.sh
