I have a web application (ASP.NET 4.0), which is running on IIS 7.0. Application is deployed on Live on June 2014 but last few days application is not working. When we are trying to access the application URL, it's displaying white blank page in browser. As a part of investigation, i have completed the below points.
- I am getting same issue when trying to browse appliction on web server.
- I have added a test HTML page to the same sub directory of application and it's working fine
- server has restarted
- no issues are thrown to the application event logs
- No issues are thrown to the IIS HHTP Error logs
- No patches were applied to the web servers
- IIS Reset
- Checked account user and pasword not issue
- Checke security log and didn't find any thing
Anyone have any idea, what is the issue.
