From CRM Server, I log on to Website http://localhost by using adminstrator
account.

In there, I can not create anything: account, contact... Whenever I want to
click the "Save" button after trying to create something, a website appear as
following:

Server Error in '/' Application
--------------------------------------------------------------------------------

A potentially dangerous Request.Form value was detected from the client
(crmFormSubmitXml="<lead><subject>asdfa...").
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.
