WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

I receive the message:

Preview mode could not be disabled. Please run chmod 777 /wp-content/w3-total-cache-config-preview.php to make the configuration file write-able, then try again.

I have chmodded the file to 777 and the error message remains.

Please rename that file to something like w3-total-cache-config-preview-backup.php, then please visit /wp-admin/admin.php?page=w3tc_general. The preview mode should have probably gone by now. –  Pothi Jan 31 '13 at 15:18
@PothiKalimuthu: Thanks Pothi. Several other errors have been removed as a result. Add an answer and I will select it. –  Steve Feb 1 '13 at 3:57
Glad to be of some help. I posted the answer with little explanation and use cases too. –  Pothi Feb 1 '13 at 8:19

W3 Total Cache plugin basically removes w3-total-cache-config-preview.php, when disabling the preview mode.

In /wp-content/ folder, please check if you have a file named w3-total-cache-config.php.

  • If it exists, please compare it with w3-total-cache-config-preview.php file.

    • If both have the same content, rename it to w3-total-cache-config-preview-backup.php and reload your site's /wp-admin/admin.php?page=w3tc_general.
    • If both have different content, please copy all the content from w3-total-cache-config-preview.php to w3-total-cache-config.php and then rename the preview file.
  • If it doesn't exist, please rename w3-total-cache-config-preview.php to w3-total-cache-config.php and then reload your site's /wp-admin/admin.php?page=w3tc_general.
