Critical Error 500 when saving menu (in nav-menus.php)

  • Hi,

    I’m using W3 Total Cache 0.9.4.

    When the plugin is active, I go to https://myblog/wp-admin/nav-menus.php, I clic on the “Save” button.

    After a long timeout it’s a 500 error.

    Only this page do this, I upgrade all timeout but nothing works. The only one issue is to disable W3 Total Cache ??

    In apache logs I can read :
    [error] [client x.x.x.x] Premature end of script headers: nav-menus.php, referer: https://myblog/wp-admin/nav-menus.php

    (The backend cache is disabled in W3 settings)

    I disabled all plugins except W3 Total Cache : error 500 too.
    When I disable W3 Total Cache, everything works.

    Any idea ?
    Thank you ??

  • xhark – What version of wordpress are you on?

    We are also on w3tc 0.9.4.

    We are having the same issue with a long timeout when trying to save large menus (containing 20ish items or more). When we deactivate w3tc, menus save fine. We are also unable to add or remove super-admin privileges for users when w3tc is activated, we get the same long timeout. I know that these two types of updates interact with more than one database table, but I don’t really understand why/how w3tc would be in the mix during a db update. We also have caching disabled for the backend, and we only use page and minify caching.
