Hi,
I tried to access to zumzi.eu, webmail.zumzi.eu and cp.zumzi.eu. Look like ok except zumzi.eu because possible no file inside docroot. Try 'sh /script/fixskeleton' or just add 'index.php' or 'index.html' in domain docroot.
You still found issue because your pc cache. Try clear browser cache and run 'ipconfig /flushdns' (if using Windows OS).
