Hmm... try clearing your browser cache... try another browser?
Have you tried rebooting the ASG yet (this is what I'd try after the browser items)?
Since you have an ASG 320, I'm guessing you have standard or premium support... if these items fail to resolve the issue for you, I'd start a case with Astaro Support.
Guys, I've seen this more than once myself. The only solution is to close all browser windows, open a fresh browser, clear the browser cache and login again to WebAdmin.
It's not browser-specific at all. The problem is that the WebAdmin page believes that it also has other content cached that it uses to display information, but it's not there. The only solution is to clear all of the cached information from the browser.
I had the same problem, I enabled NTP under Network services and then configured the NTP servers under system setting--> time and date, then I disabled NTP again now it is working fine
