I tried that Podz, but it did not work. I told myself, if Podz can't bail me out, what on earth am I gonna do. :)
So, I kept uploading and installing over and over again. I tried all possible permutations and combinations. It didn't work. I tried it uploading on a different server; it still did not work. I deleted and created databases and users over and over again on this server and that. It still wouldn't work. :O
My last resort was to try a different FTP client. And guess what? It worked! There apparently something was wrong with WS FTP. The uploading was fine with Cute FTP. I wonder why. The Auto Detect function of WS FTP seems to have a bug.
