I'm getting the above exception when I'm trying to submit a form in ASP.NET.
This post was really helpful but even after setting ValidateRequest="false"
I get this error only for "&#" combination. This specific combination is required since we are using Norwegian characters.
And I have set httpRuntime requestValidationMode="2.0"
in web.config
as well.
Ok, from the comments, I make it also as an answer.
Place the ValidateRequest="false"
on the web.config
to prevent the case that its hit on a forgotten page with out this declaration.
<pages validateRequest="false" ... >
