Support » Installing WordPress » Upgrade to 2.2 broke my blog — wp-cache-phase2 problem

  • In upgrading from 2.1 to 2.2, I received the following error:

    Warning: fopen(/home/idrathe1/public_html/wp-content/cache/wp_cache_mutex.lock) [function.fopen]: failed to open stream: No such file or directory in /home/idrathe1/public_html/wp-content/plugins/wp-cache/wp-cache-phase2.php on line 96

    My site is at I am not sure how to fix this, so if anyone could help, I would really appreciate it.

  • 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.
