Unfortunately, it's not posts I'm after, it's a copy of the txt file in my FTP directory. I was in the middle of uploading an edit I made in that file when the server disconnected. When I logged back in, there was a cached file and eventually the txt file showed up again, but it was incomplete.
Though it's true I should have taken the necessary precautions, I've been disconnected on numerous occasions while uploading and the file would remain intact. This is the first time something like this happened to me after years of use.
I'm using CuteFTP.
