I have login to the central administration of SharePoint 2013, and I have tried to create a new web application, after setting the web application values (port, database ip ,etc) and I click on OK button. The web application dialog keep showing ”working on it. This should not take too long”. So open central admin on another web browser, and the web application was there, but when I click on “general setting” I got the following error:-
Sorry, something went wrong Updates are currently disallowed on GET requests. To allow updates on a GET, set the 'AllowUnsafeUpdates' property on SPWeb.
So what is causing this error?
