"No Update Required" loop – Varnish cache issue?

  • I ran into this too. I think it’s dreamhost’s memcached caching rather than Varnish.

    I renamed the object-cache.php file to get past this too so I’m not sure, but you can try issuing wp cache flush from an ssh terminal.

    Sorry, I was out of town for Passover. patternleaf is 10000% right ??

    That’s not my plugin. That’s Memcached. You can SAFELY turn Varnish back on (please do!).

    The fix is to flush Memcached. You can ask DreamHost to do it for you, or manually type wp cache flush from the command line, while logged in to your domain via SSH.

    The cache is supposed to be flushed when the upgrade runs because WP triggers it, but there must be some race conflict in the cache invalidation check that core runs when upgrading.

    That did it! Thanks to you both–very easy fix (and the plugin is now back on :-)).
