Memcached servers are not running

    Hi,
    Just moved my site to new hosting and facing this error:” `The following memcached servers are not responding or not running:
    Database Cache: 127.0.0.1:11211.
    Page Cache: 127.0.0.1:11211.
    This message will automatically disappear once the issue is resolved.`”
    When I run a compatibility test it fails.
    This is what I get when run netstat -tulpn | grep :11211
    tcp 0 0 127.0.0.1:11211 0.0.0.0:* LISTEN 813/memcached
    udp 0 0 127.0.0.1:11211 0.0.0.0:* 813/memcached

    I can communicate with my Memcached server via telnet 127.0.0.1 11211 and execute SET and GET commands.
    I’m on php 8.0.8 and latest WP.
    Your advise on fixing this problem will be appreciated.

    Update Query Monitor gives me the following warning:

    wp-content/plugins/w3-total-cache/Util_Installed.php:145

    Hello @blackhatrus

    Thank you for your inquiry and I am happy to assist you with this.
    The Query monitor report is just saying what W3TC is reporting.
    You should look if the service is running: ps afux | grep memc
    Make sure to restart the service if needed (as root/sudo): service memcached restart

    Let me know if this helps!

    Thanks!

    Hi, Marco
    Thanks for your reply. I checked that the service is running and restarted it. Still no luck.
    Thanks!

    Hello @blackhatrus

    Thank you for the information.
    You’ve stated that the issue started after migrating to another server.
    Can you please confirm that the PHP Memcached is installed on that server because W3TC check for PHP module?
    Thank you!

    Hi Marco

    The whole issue was result of my mistake and have nothing to do with the plugin itself.
    Must admit that support for the plugin is really efficient.
    Best regards
