Error executing child request for handler in view

I have an MVC 4 view where I render the following actions

@{
Html.RenderAction("Index", "Logo");
Html.RenderAction("Index", "MainMenu");
}


I have a form on my view which is filled out and posted to the controller. In the controller I perform some tasks and then send the model back to my view

[HttpPost]
public ActionResult Index(ManageAdministratorModel manageAdministratorModel)
{
// I save some of the fields to the database here.
return View(manageAdministratorModel);
}


When I'm redirected to the view I receive the following error


Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'.


on this line

Html.RenderAction("Index", "Logo");


Any idea why this is happening?

Answer

Ok I found the problem, hopefully this will help someone in future.

The controllers for the partial views each contained the [HttpGet] attribute. For example

[HttpGet]
public ActionResult Index()
{
}

I remove the attribute from both controllers

public ActionResult Index()
{
}

and everything is now working.
