Redirect to old url after cloning

[bestbuytrading]

I tried the following steps for cloning my LIVE database to create a test environment.

 

1) URL for accessing my live site is www.bestbuytrading.com/shopping

2) Created a subdomain named 'bbttest' for my test shop bbttest.bestbuytrading.com

3) Copy the files under /shopping folder to /public_html/bbttest

4) Created a database named bbttest & a new db user

5) Login into LIVE database and exported all tables in SQL mode.

6) Login into test datbase bbttest and imported the LIVE data

7) I have modfied the table ps_configuration for the following fields to have values as bbttest.bestbuytrading.com 

        PS_SHOP_DOMAIN 

         PS_SHOP_DOMAIN_SSL 

8) Open the settings.inc.php file under the public_html/bbttest/config folder of our new test site and edit the file to change the fields DB_USER and DB_PASSWD to match the credentials we set earlier. 

 

After this If I type bbttest.bestbuytrading.com, it is going to the LIVE shop.

Not able to login to the back office if type http://bbttest.bestbuytrading.com/bbtliveadmin since pages are not displayed properly.

 

Not able to update .htaccess file through backoffice.

 

Did I have to do any more configurations?

Can you please let me know any further setting to be done regarding this/how to fix this problem?
