Upgrading from 1.5 to 2.2 via godady

It would help if we had details

(What happended before this error started to show, Was it only happening after wordpress was upgraded? What directory is WordPress installed in?)

The error your getting is beacuse GoDaddy doesn’t allow the public listning of your “/” directory. Which usually means the server couldn’t find any files like “index.php” or “index.html” to display when the request to the server came. and the “Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.” is beacuse you haven’t specified a 404 Document page or the 404 page you specified does not exsist. Meaning it got a 404 when trying to get the 404 page. (That line is a bit confusing)

I am seeing “failed to open stream” type errors suggesting that you don’t have a complete set of 2.2 files uploaded.

Please try to reupload your 2.2 files.

Is this about the site mentioned in the error message?
If yes, seemingly, not all WP files been uploaded.

Hah, MichaelH was faster by 36 seconds…

Gentlemen, thank you so much for your help.

I downloaded the package. It expands to three folders (wp-admin, wp-content, and wp-includes) with nothing in the root. Should there have been other files?

Yes, definitely a lot of files besides the 3 folders!

Thanks for all your help. I’m not sure how that happened. Probably my duh.
