We are using DNN 4.8 about a year now. From time to time we are experiencing a strange problem. Some changes made to Settings, such as Language and Banners, are lost after a few days!
For example, I created 2 new banners from the Vendors page, I set the End-Date to 30/09/2009 for the two old ones, and then Start-Date for the two new as of 1/10/2009. Everything worked fine on Oct 1st, however today we noticed that all 4 banners were visible, and when I got to the vendors page, the End-Date for the old ones, was empty!
This is not the first time it is happening, and we experienced similar behaviour for changes in the Languages.
There are only two schedules running: DotNetNuke.Services.Log.SiteLog.PurgeSiteLog & DotNetNuke.Services.Scheduling.PurgeScheduleHistory
Everything else is disabled.
What is wrong here...????
