I'm noticing that none of the historical Awstats data seem to be available in Virtualmin after migration from cPanel. I was surprised to notice that because it does seem to be part of the migration.
There's also a gap in Webalizer data for the two months immediately prior to migration.
Also, when logged in as site admin (not root), Awstats is not available under Logs and Reports. It is when I am logged in as root. The Awstats feature is enabled in Enabled Features at both the Account Plan and Virtual Server configurations.
I'm still testing Virtualmin on a server hosting only my own sites (although it is online as a production server). I do need to know how to make these features available to users before switching to Virtualmin on client sites, however. Awstats is one of the few things the clients actually seem to care about.
