Error Uploading Images I/O Error

Hey

I've been using nop commerce for a few months now with no problems, I have recently upgraded to 2.4 and after about a week of using it the new version, whenever I try to upload images to a product. It will stop uploading and give me a IO error. This is the error in the Log

  Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

  System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index at System.Collections.ArrayList.get_Item(Int32 index) at System.Web.HttpFileCollectionWrapper.get_Item(Int32 index) at Nop.Admin.Controllers.PictureController.AsyncUpload(String authToken) at lambda_method(Closure , ControllerBase , Object[] ) at System.Web.Mvc.ActionMethodDispatcher.Execute(ControllerBase controller, Object[] parameters) at System.Web.Mvc.ReflectedActionDescriptor.Execute(ControllerContext controllerContext, IDictionary`2 parameters) at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethod(ControllerContext controllerContext, ActionDescriptor actionDescriptor, IDictionary`2 parameters) at System.Web.Mvc.ControllerActionInvoker.<>c__DisplayClass15.<InvokeActionMethodWithFilters>b__12() at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethodFilter(IActionFilter filter, ActionExecutingContext preContext, Func`1 continuation) at System.Web.Mvc.ControllerActionInvoker.<>c__DisplayClass15.<>c__DisplayClass17.<InvokeActionMethodWithFilters>b__14() at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethodWithFilters(ControllerContext controllerContext, IList`1 filters, ActionDescriptor actionDescriptor, IDictionary`2 parameters) at System.Web.Mvc.ControllerActionInvoker.InvokeAction(ControllerContext controllerContext, String actionName) at System.Web.Mvc.Controller.ExecuteCore() at System.Web.Mvc.ControllerBase.Execute(RequestContext requestContext) at System.Web.Mvc.ControllerBase.System.Web.Mvc.IController.Execute(RequestContext requestContext) at System.Web.Mvc.MvcHandler.<>c__DisplayClass6.<>c__DisplayClassb.<BeginProcessRequest>b__5() at System.Web.Mvc.Async.AsyncResultWrapper.<>c__DisplayClass1.<MakeVoidDelegate>b__0() at System.Web.Mvc.Async.AsyncResultWrapper.<>c__DisplayClass8`1.<BeginSynchronous>b__7(IAsyncResult _) at System.Web.Mvc.Async.AsyncResultWrapper.WrappedAsyncResult`1.End() at System.Web.Mvc.MvcHandler.<>c__DisplayClasse.<EndProcessRequest>b__d() at System.Web.Mvc.SecurityUtil.<GetCallInAppTrustThunk>b__0(Action f) at System.Web.Mvc.SecurityUtil.ProcessInApplicationTrust(Action action) at System.Web.Mvc.MvcHandler.EndProcessRequest(IAsyncResult asyncResult) at System.Web.Mvc.MvcHandler.System.Web.IHttpAsyncHandler.EndProcessRequest(IAsyncResult result) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

I am not sure what to do, any help would greatly be appreciated.

Not sure if this will help finding a result to an issue, This webpage is running on godaddy in a sub directory. I noticed failed image thumbs appearing in a folder in the / of the webserver called "_hcc_thumbs"  never seen this folder before untill these errors started showing up.

On further investigation, Image upload works if I go to where I ad a new picture, and i select the image to upload right away. If I load the upload page let it sit open for a minuet, I receive the IO error.

I'm starting to think this is a hosting issue, or something I need to set in my web config? Has any one had similar issues?

Just some additional Information, This issue appears to of started happening once and a while from upgrading from 2.3 to 2.4, It is just as of a few days ago, every image upload gets this error.  SQL server is 2005

After trying many things. I finally got it working again! What I had to do is deploy the application in a different sub folder. Every time I would delete and re-deploy in a folder with the same name, I would still receive the error.

After Deleting the application folder, and Deleting the folder settings from IIS. I created a new folder with a different name. Set up that folder for an application in IIS. Downloaded the latest version of nop-commerce, placed my app-data files back in the app-data folder, and the images folder, and theme folder back in. (same as if I was doing an upgrade). Then I uploaded the files to the server, and visited the website located in the new folder. and set the correct folder permissions.  Everything loaded up correctly, and I was able to upload images again!

Hope this helps anyone who is having similar issues.
