Upgrade 2.2 to 2.3 turned site into spam site

I’m no expert on WP but you must give detailed information on what you’ve exactly done.

I followed the instructions here https://codex.www.ads-software.com/Upgrading_WordPress

I overwrote my old files with the new 2.3 files. Then I ran the upgrade.php script, which ran for 3-4 minutes without any error messages.

I went back to my website, prrag.com, and it was completely changed with an internal server error and this weird information.com site on it

this weird information.com site on it

Your host provided that for you.

Did you disable all plugins before upgrading?
Are you able to get to your admin stuff? https://www.prrag.com/wp-admin/

I’d consider deleting the WordPress files and reuploading as per the Step 7 and 8 in Upgrading_WordPress_Extended.

Can not get to the wp-admin folder. All folders and files redirect to the site in the screenshot

Revert to your backup, then make sure you disable all the plugins before upgrading.

Okay I deleted all the files and replaced them per steps 7 and 8 in the expanded instructions. That appeared to fix the problem. Thanks MichaelH!

It is still giving me the same error on some of wp-admin pages like
https://prrag.com/wp-admin/options-general.php

Weird — the site was working fine when I followed steps 7 and 8 and now, all of a sudden it’s right back to the way it was when I posted

https://www.prrag.com

looks fine to me. Check your cache.

yep – looks fine to me, too.
