Thanks for your comment.
For others this shows the importance of Firebug!
Solved Amitbaghel problem by using Firebug and seeing when doing any admin functions keep getting 404 Error for website/api/SomeAction
Also it is best to download locally unzip BE, then make sure it works locally and etc, then zip up the folder /BlogEngine.NET then upload the zip folder
not ftping the folder and files one by one.
Once zip folder is on server unzip it there.
That way prevents missing files or folders and also much faster.
Better method if you use Visual Studio is Web Deploy!
