HTTP Error 500.19 - Internal Server Error localhost

4.8k views Asked by At

newbie here, I am having an error in all of my projects and backups when executing my project visual studio 2012. Last week it was working fine and then the error came out. I am just using localhost.

these are solutions that i found and it still didn't work: :(

-In IIS Manager - Feature Delegation set HandlerMapping to Read/Write.

-Control Panel, Turn windows features on or off, Internet Information Services, World Wide Web Services, enable Application Development Features except CGI.

-I gave IIS_IUSRS full control to my project folder.

Any other suggestions?

according to me there should be problem in your application pool.. Just change and select proper version 4.5 pool to solve your server problem.. If still not work for you then inform..
