1) download Serendipity 1.03 (latest version) to your computer. Extract files.
2) Remember where the Serendipity folder is, leave them there; then go to your GoDaddy account.
3) After logging on, go to my account, go to hosting, then to manage, then to Ftp file transfer. (GoDaddy users will know how to do this). Click on that, and two boxes will open. There is a warning above that the Ftp will not work on large file transfers. Have faith. I did it somehow, and so can you.
4) You will see the Serendipity folder in your uploaded files (in right box). Perfect, no problem. Now go to the left side box and search through your computer files till you find the Serendipity folder with all the extracted files. NOTE: this is not the Serndipity_1.03 folder, but the one inside that, just plain Serendipity (just like the folder on the right side of the screen).
5) Now you have one Serendipity folder on the left side, and one Serendipity folder on your right side. Click on the little transfer arrow symbol that points right. The transfer (upload) will begin.
6) This took about 10 minutes at DSL upload speed. There will be lots of flashes and little messages as the process continues. Finally, it will say transfer complete.
7) Log off GoDaddy. Go to your browser favorites and click on your blog address. It will not come up. Your website is destroyed and..No, wait-It's a message from Serendipity stating just a few more things need to be done. It will walk you through. The first message says it knows you are attempting to upgrade, which made me feel uncomfortable enough to draw the blinds tighter. I wish they wouldn't watch all the time...
Also, if you modified a template that you are using, and never bothered to use the "save as" function, as I didn't, and the template still retains its original name, upgrading will override it again. So if you are using MT-Georgia Blue, for example, with your mangled mods in there, you better delete the Mt-Georgia Blue from the upgraded version before you upload.
Or, you can just upload and start fresh and clean. Of course, there is no chance you'll remember any of your changes because, if you are like me, you wrote nothing down.
This post was probably excruciating to experienced programers, but if I saved the life of just 1 newbie, it was worth it!
My Php training (pretty helpless, practically) has been interesting. Its like a different language or something
Thanks again, Carl, for your help. And to Bexter for that awesome template I mangled, but only a little.
