Universal Studio shows 404 not found in CE

Hello all,

I have been experimenting with Kaltura CE for several weeks now. I have what I thought to be a successful deployment in an AWS EC2 instance. I have a single server install running on CentOS. I have gotten to the point where I am attempting to create my own players. When I navigate to the studio tab in KMC and click on “universal studio” I get a 404 not found error for /apps/studio/v1.9/index.html.

I found the /apps/studio directory on my server and it has a “v1.8.1” folder in it. I did attempt to rename that folder to “v1.9” and retried the link in KMC. At that point it just loaded a blank white page. I could use some help on how to go about making the universal studio work.

Thanks for your time.


The version you should have with 9.19.8 [latest version] is v1.9.1.
I suggest you follow the upgrade proc here:

Once aligned with the latest, if it still does not work, check the error logs and the JS console in your browser’s dev tools and paste here.

Hi Jess,

That worked out great. Thanks for the easy fix. I am curious tho…

I did my install 3 weeks ago, why didn’t I get the latest versions at that point? Did I do something wrong with the install?

Thanks again,


Hi Ken,

It was a mistake on our end, the kaltura-html5-studio was not pushed along with kaltura-base at the time and then, shortly after it was pushed. I believe it was just around that time.

Anyhow, happy to hear you’re good.
