After transfering files (html pages and some images) to hard drive, changing them and uploading back, web-site pages broke…
I was trying to upload backup – the same story.
My angel told me (I won’t think about it by myself:) to check FTP transfer type. I’ve noticed it is set to Binary. I forgot to switch it back to ‘Auto’ after some specific files upload.
In my case I needed to upload “clean” images from my very old backup to start web-site’s pages working properly again.
For vast majority of your work 'Auto' type should be used
But! Changes did NOT appear immediately. When I was devastated by looking into this problem solution everything started to work fine again. It means the server needs some time to ‘recognize’ old-new files transferred in a ‘right’ FTP type.
Note: in most cases you don’t need to experiment and just set up your FTP transfer type to ‘Auto’
