[pmwiki-users] RecentChanges stopped logging. why?

[Stephan Schildberg]

Hello,

by the time I upgraded to 2.1.1 Main/RecentChanges it appears that it 
stopped logging on 14th March 2006 since December 4th 2004 for an 
unknown reason. Now I upgraded it to 2.1.5. Still no reaction.
How can I restart that mechanism and how I can delimit the visible 
period in RecentChanges to 185 days?

This does not make it fully clear to me.

regards, Stephan.
