Jitsi focus error after modifying UI

Hello again!
After modifying UI with [How to] How to build Jitsi Meet from source: A developer’s guide - Developers - Jitsi Community Forum - developers & users

I always got focus error and conference disconnected. I don’t configure any files except modifying the UI.

Here are some jicofo logs error.

Anyone can help me?
Thanks!

Check your Prosody logs, there might be some clues there.

Your prosody is not configured correctly.

But, I don’t configuring prosody… Just installing it via quick install guide…

Then the default configuration is not OK for Jitsi

So, it must configured? What i must configure? I don’t have any idea for this…

According to the logs, prosody cannot load the modules. The plugins folder seems wrong. It should point to the correct folder which contains the modules.

This is /usr/share/jitsi-meet/prosody-plugins/ in a typical setup

It works, thank you so much @emrah, appreciated it!
