In last week while working with magento store, we have a requirement to change the copyright text at footer.
At that time I haven’t proper idea to change copyright text at footer.
So I have searched the web and found proper way to satisfy our requirement.
And here is the proper way:
First go to your magento store admin.
Then click on System -> Configuration from header menu.
Now go to Design from left side.
And change Footer -> Copyright text according to your requirement.
Hope this will help you.
