I read the default patch documentation but I do not understand how to apply it on server like bluehost, can someone help me with it please thank you.
Your best bet is to apply the patch locally and then pull the changes to your server. (In this case Bluehost). However, I doubt that Bluehost has any such sophistication such as Git or SSH so you might simply have to upload the changes that you made locally via FTP. -- But, this assumes you have a local dev environment setup with Git and SSH.
