Hi,

I am using DNN Community v06.01.02 and I am getting an error when clicking on File Manager within admin.

DotNetNuke.Services.Exceptions.PageLoadException: A potentially dangerous Request.Form value was detected from the client (dnn$RibbonBar$EditPage$SkinLst="<Use Default Site Sk..."). ---> System.Web.HttpRequestValidationException: A potentially dangerous Request.Form value was detected from the client (dnn$RibbonBar$EditPage$SkinLst="<Use Default Site Sk...").     at System.Web.HttpRequest.ValidateString(String value, String collectionKey, RequestValidationSource requestCollection)     at System.Web.HttpRequest.ValidateNameValueCollection(NameValueCollection nvc, RequestValidationSource requestCollection)     at System.Web.HttpRequest.get_Form()     at System.Web.HttpRequest.get_HasForm()     at System.Web.UI.Page.GetCollectionBasedOnMethod(Boolean dontReturnNull)     at System.Web.UI.Page.DeterminePostBackMode()     at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)     --- End of inner exception stack trace

Does anyone know why?

Thanks

please check your web.config and ensure the httpRuntime node has requestValidationMode="2.0" (this should happen automatically under .net 4.0-so also check your permissions as it may be that DotNetNuke cannot correctly update the web.config file)
