How do I connect to FTP/SFTP to manage OpenCart files?
For FTP/SFTP connection use tools such as FileZilla. You need: hostname (usually your domain), username/password (by hosting provider), port (21 for FTP, 22 for SFTP). Use SFTP for safety. Upload files to the public html folder or equivalent. Configure the defaults (755 for folders, 644 for files).
