  • Hi friend,

    Two suggestions for you to try :

    1 Please make sure that the App Pool identity has the correct authorization to the site's path.


    2 Restarting IIS solved the same issue in others’ case if something fails in IIS.

     Run Command Prompt type: iisreset


    Let me know the result after your trying.

    Have a nice day:)
