I've installed the EPiServer 7.5 version of CMO against an MVC site at EPiServer 7.9.x, then installed the CMO Nuget version 7.5.446.2.
CMO itself works, but the image thumbnails aren't being generated - in the EPiServer log, I see the following:
2014-10-23 16:33:55,997  ERROR EPiServer.Global: 1.2.5 Unhandled exception in ASP.NETSystem.Web.HttpException (0x80004005): The controller for path '/epi/CMO/thumbhandler.axd' was not found or does not implement IController. at System.Web.Mvc.DefaultControllerFactory.GetControllerInstance(RequestContext requestContext, Type controllerType) at System.Web.Mvc.DefaultControllerFactory.CreateController(RequestContext requestContext, String controllerName) at System.Web.Mvc.MvcHandler.ProcessRequestInit(HttpContextBase httpContext, IController& controller, IControllerFactory& factory) at System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContextBase httpContext, AsyncCallback callback, Object state) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
I assume that I need to exclude the route mentioned above, but was under the impression that all *.axd requests were already ignored.
Has anyone else encountered this (and fixed it)?
There was some custom routing on the site which messed up the default routing, so I had to add the exclusions again.
