WP Super Cache
502 error with Haproxy (load balander) (2 posts)

    Hi,

    When I'm connected as WP Admin, I often obtain a :

    "502 Bad Gateway
    The server returned an invalid or incomplete response."

    When I disable WP-Super-Cache, it works without this issue.

    My hoster use a haproxy load balancing.

    Do you know this issue ?
    Thank you.

    Sincerely

    That's strange because Supercache should get out of the way when in the backend. Any errors in your PHP error_log? I don't know where that log file is so you might need to search for it.
