(See the change record for more information on why this warning was added, and these instructions for how to ensure that warning messages like this one are never displayed to your site's end users, but rather only recorded in the administrative logs.)

If you see a PHP warning such as 'The following module is missing from the file system.' (or similar) on your site, this page explains how to fix it.
