Hi,
What does /opt/kaltura/apps/studio/v*/studio.ini contain?
It should have:
component.version set to the studio version, i.e:
rpm -q kaltura-html5-studio
and html5_version set to the version returned from:
rpm -q kaltura-html5lib
There version for the HTML5 lib should also be set correctly in /opt/kaltura/app/configurations/local.ini, directive name is html5_version.
Can you check what values you have?
