How to configure Magento to work with a new domain

There are two things you should do in order to configure Magento to work with a new domain:

Edit the Magento database
Go to your cPanel > phpMyAdmin. Select your Magento database from the left menu, find the table called core_config_data and click on it.

Click the Browse tab and edit the first two fields:

web/unsecure/base_url
web/secure/base_url


by clicking the pen icon in front of each of them. Replace your old domain name with your new one and click the Go button to save the change.

Clear the Magento cache.
The Magento cache folder is located in your Magento installation directory > /var/cache. To clear the cache, simply delete the folder.

Many Magento issues can be fixed just by deleting the cache.
