When you receive an error about incorrect FTP login we recommend changing your cPanel / FTP password.
If you are a SiteGround customer, you can do this from your SiteGround Customer Area > Manage next to your account. There you will find the option to change your cPanel / FTP password.
If you are using an additionally created FTP account, you should make sure to add @yourdomain.com after the FTP username. For example, your username should be ftpuser1@yourdomain.com if you have created an FTP user with username ftpuser1 and your domain is yourdomain.com.
