Uploaded new 3.0 and now I cannot access my blog

After auto-upgrading to 3.0 I lost my website. After reading in the forums I got the impression that it was a plug-in issue, so I deleted all the folders. I left hello.php and index.php. I then got a different error message = Fatal error: Call to undefined function is_multisite() in D:\Hosting\6120655\html\wp-includes\wp-db.php on line 505.

I don’t mind deleting whatever you suggest, I’ll go back and re-download the pug-ins or widgets. I can only access my fie manager – not dashboard.

You wp helpers are always so good at getting us out of jams… you poor guys and gals must be swamped… thanks in advance for any help. Stay positive and we’ll get through this ??

@triviafrog: Re-upload all 3.0 files & folders.

Switch to the 2010 theme by renaming your current theme’s folder.

Reset the plugins folder by FTP.

That might get you back up & running. There’s a list of known problematic plugins etc at https://www.ads-software.com/support/topic/411649

Well, I dowloaded my data base. Unistalled WordPress, reinstalled WordPress 2.9.2.. restored everything and now nothing works. I get this message:

“Forbidden You don’t have permission to access / on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.”

What a mess! Why did WP come out with something that is not ready for all the plugings etc. The only way to fix this is to pay WP ….and that cost is $100. per hour!!!!!

I don’t want to do that! Is there any way I can get someone to help me without paying that kind of fee?

I’m closing this thread now to avoid any bidding wars.
