Live link problem?

I just try to enable your Live Link function, but I got problem to disable it.
Cause once disabled, I got only this message:
Tunnel not found
So I stop and restart computer but I can’t access my website anymore without the Live Link.
(I’m not using cache plugin actualy)

How to solve that please?

Hi, I found the responsible plugin: polylang pro
So what can I do exactly now please?
