Hi BEguys,

My company recently migrated to a new web server so as IIS 6.0 to IIS 7.5.
We are using SQL Database setting for the BLOG, and everything works fine but BLOG part.

Http://../blog/login.aspx is working strange.
After I login as a Admin, nothing happens. But, I am able to see BLOG "Control Panel" link.

when I click "Add Entry" link, I got the Error below:
"Profile", "Users" links have similar errors like this.

"Control","Categories" and "Settings" are working fine.


Server Error in '/' Application.
