WordPress is free, powerful, and extremely easy to use, making it the perfect engine for running a website even if you have no coding knowledge. By default, WordPress always shows a “Powered by WordPress” link at the bottom of each page. While it is certainly fine to give WordPress a bit of free publicity, you may not always want visitors to know that your website runs a free blogging engine. If you want to remove the WordPress link from your website, you can do so by editing the footer.php file for your WordPress theme.
We’ll use the “twentyten” theme, which comes with WordPress, as an example.
Connect to your server using an FTP client. Open the “wp-content” and “themes” folders, and then open the folder for the theme that you are currently using.
Done. Visitors to your website will stop seeing the WordPress link immediately.
If you have an Elegant Themes WordPress theme installed, you might notice that the footer.php file looks a bit different, containing links to both the WordPress and Elegant Themes websites.
To remove the WordPress and Elegant Themes links from the bottom of an Elegant Themes footer.php file, remove the area highlighted in the image to the left. While all of the Elegant Themes footer.php files are not exactly the same, it is the same general idea for each one.
