Hi Friends,

I have a domain and i did manage the site pages in that domain. For example, my hosting domain virtual folder is "public_html". I have managed the site pages in this folder. Also I have created a folder called "test" and set virtual path under the "public_html" folder. "test" is used to fix the bugs and before release the "public_html" folder. Initially we did not used to update data in database. just manage contents only for. Right now i have used to update data in database. So i am using some class library to insert/update the data to database. once i did publish and release these changes to "public_html" folder. Now it is working fine. And then I moved these also to "test" folder.

In "test" folder, i got following unhandled error when run the pages in "test" virtual directory.
