Error in meeting

I have installed on my server and all was good. Now meetings crash. See
Can I get help? I have customizing I need too.

What are we supposed to see at that URL? It’s not valid.

Sorry the site goes down alot. Try now.

It errors when you start a meeting in a few seconds too

You’re running an awfully old version of Jitsi. You need to upgrade - like immediately.

ok thanks
