CMO trying to set cookies after headers have been sent.
After starting a CMO test in Episerver 7.5, my errors log is nothing but these errors:
2015-07-17 23:59:01,459 [37] ERROR EPiServer.Global: 1.2.5 Unhandled exception in ASP.NET
System.Web.HttpException (0x80004005): Server cannot modify cookies after HTTP headers have been sent.
at System.Web.HttpCookieCollection.Set(HttpCookie cookie)
at EPiServer.Cmo.Cms.HttpModule.LpoPageSwitcher.GetVersionPageReference(PageReference requestReference)
at EPiServer.Cmo.Cms.LpoPageDataHandler.GetPageData(PageReference reference)
Any clue as to why CMO is doing this?
