I have an MVC 4 view where I render the following actions
@{ Html.RenderAction(\"Index\", \"Logo\"); Html.RenderAction(\"Index\", \"MainMenu\"); } >
I just got this error occurring in my razor when my partial view had a code formatting error in it.
If you click 'Continue' to get past the error, you'll see the actual error message displayed in the browser window that you loaded it from.
Correct the error in the partial view and it'll work!
