My website is working perfectly fine on local server but not after i publish it on ftp. After publishing my first view to choose login panel works fine and is working fine but other pages are giving this error given below. Also someone told me the problem could be because u r using iis express 10 while version 7.5 is available on server. After i uninstalled version 10 and installed version 7.5 new projects are working fine but not those projects which were made with version 10 of iis express. I have tried every solution possible on net but nothing worked for his error so am posting this question again...please help
