Warning: db.php not found

  • I took over the management of a website recently for my organization and I’ve started seeing this error occasionally:

    WARNING: wp-content/plugins/w3-total-cache/lib/W3/DbCacheAdminEnvironment.php:155 - file_get_contents(/wp-content/db.php): failed to open stream: No such file or directory require_once('wp-admin/admin-header.php'), do_action('admin_notices'), call_user_func_array, W3_Plugin_TotalCacheAdmin->admin_notices, W3_AdminEnvironment->fix_in_wpadmin, W3_DbCacheAdminEnvironment->fix_on_wpadmin_request, W3_DbCacheAdminEnvironment->delete_addin, W3_DbCacheAdminEnvironment->is_dbcache_add_in, file_get_contents

    I’m not familiar with /wp-content/db.php as it’s not a WordPress core file. What is it’s purpose and how do I fix this error?

    I’m running v0.9.4.1 of the plugin on WP4.4.2 and php 5.6.

    Thank you in advance for any help with this issue.
