Actually, I accidentally left some old DDR stuff in my web.config and it still works!
I don’t know if this was intentionally left in the ActiveReports engine from the DDR code, but here is what I used:
<system.diagnostics> <switches> <add name="DataDynamics.Reports.Web" value="4"/> </switches> <trace autoflush="true" indentsize="4"> <listeners> <add name="Reports" type="System.Diagnostics.TextWriterTraceListener, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" initializeData="ActiveReports.Trace.log"/> </listeners> </trace> </system.diagnostics>
(I changed the name of the log file on the 'initializeData="ActiveReports.Trace.log"'; it used to be "DataDynamics.Reports.Trace.log")
Hope this helps someone else!
