You can make small changes directly in your browser under your server → Files. For large uploads, SFTP is faster, for example with the free program FileZilla.
Login details
- Server, port and username are shown under your server → Files (the “SFTP access” box).
- Password is your client area password.
How to do it in FileZilla
- File → Site Manager → New site.
- Choose the SFTP protocol and enter the server, port and username.
- Connect, then simply drag and drop your files to upload them.
After uploading mods, restart the server once.
