- 1). Connect to your Web server using an FTP program. FileZilla is a free, open-source FTP program that you can download if you do not have one installed. When you create an account with a Web hosting provider, you should receive an email containing instructions on how to connect via FTP.
- 2). Open the "wp-includes" directory on your Web server.
- 3). Download the file "pluggable.php" and open it with a text editor, such as Notepad.
- 4). Press the "Ctrl" and "F" keys simultaneously to open the "Find" dialog box. Search the file for the phrase "Your username and password." This brings the cursor to a line of code that looks like "wp_mail($user_email, sprintf(__('[%s] Your username and password'), $blogname), $message);".
- 5). Place the cursor in front of the phrase "wp_mail." Type two backslashes and a space. The line should now look like "// wp_mail($user_email, sprintf(__('[%s] Your username and password'), $blogname), $message);".
- 6). Save the file "pluggable.php" and upload it back to your Web server. WordPress will no longer send messages to new subscribers.
