I have two files, one is zip file with pdfs ebooks and another is a mp4. Before I upload those file to my ftp via filezilla, I tested them out and they open perfectly.
When I download them from the website links as if I am a regular visitor, they zip does not open (I use jZip), and the video's format becomes unrecognizable when playing it with any video player.
So upon uploading to ftp and then downloading, the files becomes unaccessable, any reason as to why this is happening and what should I do about it?:confused:
