Seltsame Fehlermeldungen

[xDeathList5x]

Hallo, habe seit geraumer Zeit im Adminmenü unter Manage Boards and Categories folgende Fehlermeldung stehen:

Server Error in '/' Application.
A potentially dangerous Request.QueryString value was detected from the client (refurl="...tion.</a> <a href=").
Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.

Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.QueryString value was detected from the client (refurl="...tion.</a> <a href=").

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Ich kann keine neuen Boards mehr erstellen oder etwas verÃÆ'Ã,¤ndern. Kann mir jemand sagen was das für ein Fehler ist und wie ich den weg bekomme.
Habe schon mehrmlas mein Forum neu installiert aber der Fehler bleibt.
Liegt es an der Datenbank?

Ist das ein Shared Hosting Windows Server oder ein eigener Root / Managed server auf windows basis ?
