Vesta Control Panel - Forum

Hello,
I have a strange problem with Roundcube. Firstly when I installed Vesta on my Debian I downloaded Roundcube 1.1.0 and updated with installto.sh script with config files update. All done, everything working. I tested some options and I was suposed to reinstall server. After that, I installed fresh Vesta and when try to update roundcube - the same installation files! I getting this error: I reinstalled system several times and always I getting this error. After that I can't use roundcube.
Someone know why firstly I passed this install without a problems?

I solved the problem. After fresh install of Vesta CP i was have 2 installations dir
var/lib/roundcube
&
/usr/share/roundcube

Firstly when all was fine i run installto.sh script with var/lib/roundcube path.
Next time I ran with /usr/share/roundcube and update crashed.

Why there are 2 installations dir? I don't know. Everything working now perfectly.

I need clarification on this. Why there are 2 installation directories. If we want to update, which folder should it go?
