I have installed and configured DNN 9 under a subdomain like dnn.mysite.com, pointing to a folder like mysite\dnn. All works fine there.
Now that my tests are ok I`m trying to promote it to Production by changing my main domain (www.mysite.com) to point to the same folder as the subdomain (from mysite\wwwroot to mysite\dnn). I was expecting this change to work smoothly but instead I get the following error when accessing the main domain:
[NullReferenceException: Object reference not set to an instance of an object.]
DotNetNuke.HttpModules.OutputCaching.OutputCacheModule.OnResolveRequestCache(Object sender, EventArgs e)
Does anybody know what can be wrong here?
