I am trying to access my local website using FTP so I can add some code to functions.php. I am on a Mac OS 15.3.2 and from what I understand I can access the server at ftp://127.0.0.1 but when I enter a password I get an error
There was a problem connecting to the server “127.0.0.1”. This file server will not allow any additional users to log on. Try to connect again later.
An easier method might be to click on Site Folder in your Local application, and then go to App > Public > WP-Content > Themes > (YourTheme) > And then you can grab your functions.php and open it with an editor of your choice. When you’re done making changes you’ll want to Save, Stop and Restart your Local site to make sure those changes stick.
As far as FTP goes you should be able to navigate similarly. I just tested it with my Transmit setup. You can start with your Local Sites folder and drill down from there.
