FTP Filezilla Error: Can’t Open Data Connection
I am uploading image content in my blog using my FTP FileZilla client. It was very helpful since the transferring process is fast and you can upload pictures in bulk. But when I logged out and then tried to logged in the other day, I was able to log in my FileZilla but an error message "Can't open data connection” appears. Then an error message Failed to retrieve directory listing also appears. After that, my connection was closed by the server.
I use my FileZilla on my customized website generated through custom-made CMS. What can I do to prevent this error?
