    Hi @yworld,

    I think that timeout causing when accessing to Memcache server. It uses localhost/port (127.0.0.1:11211) by default. Can you confirm that Memcached installed and you are able to access it?

    (When activating a persistent object cache backend, you will need a driver and the service that runs on the server)

    If your memcache server is different than localhost, you can define the server address in wp-config.php file such as:

    
$memcached_servers = array(
    'default' => array(
        '10.10.10.20:11211'
    )
);

    Please check this and let me know if you have any other questions.

    How to properly exclude pages from caching(object cache):

    You can’t exclude pages from the object cache (neither you should) but you can exclude it from the page cache under the advanced settings.

    Cheers,

    Yes, everything is fine with Memcached installed.
    wp-config.php(does not work if via socket) connection drops intermittently.
    I wrote the socket directly to memcache-object-cache. I’ll see what happens next while it works.
    Thank you for your attention to the question!

    The plugin works fine with php 8. Add isset in a couple of places and the warnings go away. But these are trifles and take your time.

    @yworld,

    The socket should be supported fine with something like – https://wordpress.org/support/topic/memcached-with-unix-socket/#post-3939166

    The plugin works fine with php 8. Add isset in a couple of places and the warnings go away. But these are trifles and take your time.

    Actually, I’m not maintaining drop-ins directly, just porting them in the plugin for ease to use. If you feel comfortable, you can use https://wordpress.org/plugins/memcached/ too. I will check the other codes for PHP 8 compatibility for future versions.

    Thanks for the feedback

    Got this error again. I will be glad to any hints.

    Would you mind giving a try to port instead of socket?

    Changed php_value max_execution_time 300. Perhaps this is the case.

    No need to add port, it already parses the line in the file memcache-object-cache and adds the port 0:

    $memcached_servers = array(
  'default' => array(
    'unix:///****/*****/.memcached.sock'
  )
);

    I’m checking it while it works.

    @yworld,

    I’m not sure if you need to change max_execution_time value, Memcached access should be fast to get benefits from it. FWIW

    The error occurs several times a day. In the meantime, I will check with php_value max_execution_time 300. Then I will decrease and check.

    Thank you!

    It’s hard to explain in English, but I’ll try.

    I found out that the problem is in some changes in wp himself. The scripts(memcache-object-cache.php) are old enough and don’t take this into account. Therefore, the problem arises, but so far only on all sorts of non-standard and technical pages. Maybe I’ll take a moment and try to fix this issue in the future.
    In general, everything works fine and there are no special problems with normal pages.
    You made a great plugin, thanks again. You don’t need to change anything.
