A potentially dangerous Request.Form value was detected from the client (ctl00$PlaceHolderMain$forum$ctl03$UserBox="<yaf:avatar /><div c...").
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. To allow pages to override application request validation settings, set the requestValidationMode attribute in the httpRuntime configuration section to requestValidationMode="2.0". Example: <httpRuntime requestValidationMode="2.0" />. After setting this value, you can then disable request validation by setting validateRequest="false" in the Page directive or in the <pages> configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. For more information, see http://go.microsoft.com/fwlink/?LinkId=153133 .

Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Form value was detected from the client (ctl00$PlaceHolderMain$forum$ctl03$UserBox="<yaf:avatar /><div c...")."

Your YAF is running under .NET 4.0 - you must add/modify the following lines to your web.config (inside the <system.web> section):


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


You should also be running the .NET v4.0 Binaries.
