Item14480: VISITORS & NRGUESTS returning no results

I recently noticed in site updated to latest Foswiki (2.1.4) that the %VISITORS{}% macro is not returning any results and %NRGUESTS% always returns "0", even though I confirmed that there were both authenticated users and guests on the site (by monitoring events.log ). The LASTVISITORS and NEWUSERS do seem to be working as expected.

That's a side effect of changing the session file format to Storable from the default Data::Dumper format. It was changed by Item13563 in order to support unicode WikiNames.

The solution is to use the CPAN:CGI::Session ->find() call to search the session store rather that reading the files directly.

Note that counting of guests and visitors will become unreliable if Guest Sessions is disabled. For public facing sites, that's a good thing to use. It prevents the search bots from flooding the session store with useless sessions.
