When working in various set up stages of CiviCRM, a new member page or contributions page I often get this error message:

The requested URL could not be retrieved While trying to retrieve the URL:.... The following error was encountered: Zero Sized Reply. Squid did not receive any data for this request.

Is this only because WordPress failed to auto update? Is this something only my Cache Admin can solve?

  • I use varnish instead of squid as a front-end proxy, but I've had similar issues from time to time. You'll want to check quite a few server logs for hints (php, http, and squid). It might be as simple as a timeout error, or it might be more subtle involving a php configuration. – Alan Dixon May 31 '17 at 15:40
