webalizer -authentic theme - monthly links broken?

When viewing a webalizer report in authentic theme, clicking on the monthly dates to view details of the month goes no where. Link in address bar changes to


But the right browser frame doesn’t change. Continuing to click on month dates yields the links just being added onto the current address bar like below.


If I go to generate report and click view reports from that page, all the monthly links work fine, right frame changes to the monthly details.

Links/reports work fine in virtualmin framed theme. Anyone else? Or should I change to awstats? Which one are most people using?

Ubuntu 14.04
Virtualmin version 6.02-2 Pro
Webmin version 1.872
