The error is telling you that it cannot find a model with that name.

When uploading to a live server make sure you upload with the option to have all filename lowercase, some web servers are case sensitive.

Check your model directory and see if that model is in there.

[eluser]Harish[/eluser]
It can be work on the local server

[eluser]InsiteFX[/eluser]
Did you set your config base_url to the new web sites url?

[eluser]Harish[/eluser]

It means you have used client instead of $client in your model. Is it?

[eluser]Harish[/eluser]
actually client is a controller..

Please copy the login model code. Also remove any space before or after php tag to remove the header already sent warning.
