Hi, i have a fresh install of v6 with a hosting service. I setup a new site within Kentico and am getting a error "A potentially dangerous Request.Form value was detected from the client" when attempting to remove webparts from the default templates.

I found a couple threads relating to the same issue and have tried adding:

<pages validateRequest="false"/>
<httpRuntime requestValidationMode="2.0" .../>

To the <system.web> area in the web.config but this did not stop the error.

All source files are completely standard as it is a new install, the only thing changed in the entire solution is the web.config (all that is changed is the above).

I am able to use the rest of the site as normal, create edit & remove documents... the error only seems to appear when attempting to remove webparts from a page.

IIS7
ASP.NET v4

Please could someone advice how to resolve the issue, Thanks a lot, Anthony.
