Hi abcx,
I did resolve the problem. I don’t know if you’ll be able to do the same thing that I did – but what I did was install another copy of wordpress at /blog2/ and using the same database, just a different header (so instead of wp_, it was wp2_)
The thing to do then is to rename your wp_options to something else – wp3_options is what I named it- and then rename the wp2_options of the fresh install to wp_options (effectively giving you a fresh install of the wp_options). This will take away all your previously installed settings but did resolve the problem, and it was easy enough to set up.
However, there may be a way you can avoid all of this. I suspect the underlying problem was due to my FAlbum plugin – although I had disabled the plugin and changed the name of the folder, there was a call to the plugin in my sidebar. Whenever the browser tried to parse the plugin, it failed, resulting in a half-rendered page. I’m not sure if this is also what was affecting my ability to log in or not, but I think that’s at least partway responsible for some of the problem.
Of course, before you try anything make a backup of your database first!
Best of luck,

Well, I upgraded back up to 2.6.2. Same problem. Site is partially displaying. If I try to login now though, nothing happens when I press “Login” after I enter my credentials. Looks like the browser is going somewhere but stays at the login page.

Meanwhile, spammers continue to post comments and I get hundreds of approve/reject messages I can’t log in to delete!

Bump, anyone got a clue? I still can’t log into admin and the sidebar is not working, but the site seems to be running and I’ve gotten a million spam comment emails as all plugins are disabled :/

Still no joy, just a blank page. I put back the theme because at least that way my posts are displaying. Still can’t log in, redirection warning keeps appearing.

I did disable plugins prior to upgrading, but I’ll try what you suggest (backing up plugins/rename folder/rename theme).
Thanks.

Because my weblog is at /blog?
In any case, I semi-resolved the issue by overwriting wp-admin, wp-includes, and the root wordpress files in /blog/ with those of wordpress 2.5.1. I then performed an upgrade of the database… with the result that my posts work:

But little else. When I try to log in now, or go directly to wp-admin, I get a Redirect Loop warning (Redirection limit for this URL exceeded. Unable to load the requested page. This may be caused by cookies that are blocked.) in Firefox.

I believe your issue might be resolved here:

Try that?

Edit: Going to your URI, seems like there’s another hack attack over there.

Anyone got an idea?

Renamed custom theme folder, I’m just getting a blank page now. Same problem when I try to login (/wp-login.php) as well, I enter my credentials, press Log In, it seems like a page is loading and nothing happens.

I just upgraded the site using the upgrade guide – make backup, disable plugins, delete wp-admin and wp-includes and replace, and then update wp-content and the files in the root directory. Unfortunately I can’t log in to change the theme, it opens the login page but entering my crendentials and pressing “login” results in nothing happening.

If I change the name of the currently-activated theme directory will it revert back to the original theme?

Tried that, no joy.

I removed the contents of my wp-config.php file and copied in the contents from the wp-config-sample.php, updating with my information, which resolved the issue somewhat. I can’t log in now, and the page only partially loads. Thanks for your help though!
