Jigasi subtitle not working

I am using the 7287 jitsi version. When I click on Start Subtitle nothing happen.

I go for jigasi log but there is no error in jigasi log.
I don’t see any symptom of error.
Could you please help me.

Please update to the latest stable version.

Which version should I use please give advice?
