In my SharePoint 2013 after creating web application and site creation the site is not opening and its throwing following error.Why its happening,please someone help for this.
Did you make any manual changes to the web.config file? Looks like there is safe control entry in web.config file that is causing the error (in your screenshot the line that is highlighted). The safe control line is not correct and probably also not in the correct node. Try removing that line from web.config file.
