InstantWp – Login Error

Hi,
Login Error in InstantWP. Default : admin/password not working.

I was moving a complete site in InstantWp for testing with some new plugins.
I copied the wp-content and replaced with the wp-content folder in
…..\iwpserver\htdocs\wordpress on my desktop.

I exported the .sql file of the correct database and imported it as such through the phpMyadmin of IntantWP. Do I suppose to change something in that file?

I searched documents and internet for this : and changed the user’s password in the wp_users table in the database.
Using that password also shows error on the log in screen.

Keep in mind, I still haven’t changed anything in the .sql file.

I have also changed the site_url in the wp_options table from the actual address to http://127.0.0.1:81/wordpress/ as the InstantWp was showing.

Please, tell me what I forgot to do?

Thanks in advance,
Ankit
