Upgrade to 2.2 broke my blog — wp-cache-phase2 problem

I think my problem is related to a wp-cache plugin that I previously installed. I deactivated it before running the upgrade, but maybe I needed to totally wipe it from my database too. Any help out there?

I went into my wp-config file and removed this line:

define(‘WP_CACHE’, true);

Then I deleted all the appropriate files and reuploaded the right ones; then I ran the upgrade script and received this error:

Fatal error: Call to undefined function: timer_start() in /home/idrathe1/public_html/wp-admin/upgrade.php on line 7

@tomjohnson. I have had this too. WP-cache makes a shortcut file in the wp-content folder. probably you have deleted this when you installed the new files.
You have to deactivate wp-cache AND delete the line in the wp-config file. Since you already upgraded, deleting references to wp-cache plugin in the database could help.
When you reactivate wp-cahce the shortcut will be put back in wp-content.
I haven’t seen the timer_start error you mention. Maybe another plugin is causing that?

Thanks macbrink. I think I will make sure I remove every reference to wp-cache in wp-content, wp-config, and plugins, and then I’ll try the upgrade again.
