    Reply To: session_start(): Cannot find save handler ‘mm’ – session startup failed in /site, by apolloman

    hello dear Josh,

    first of all: many many thanks for the quick reply.

    no – this is part of the system logs that i can see in webmin:

    I recognized this while looking for some mail functions that i need in the plugin
    participant-database – see this thread: https://wordpress.org/support/topic/e-mail-notification-mails-to-admin-and-subscriber-do-not-work/

    Note: i can send mails successfully – using two different WP-Plugins:
    – WP Mail SMTP (by wpforms)
    – Easy WP SMTP (by wp-ecommerce)

    So i had to check the whole system – and while doing so – i recognized the issues – i saw the errorlogs

    i did some more investigations:


    This error means that our (my) session can not be saved by our session save handler. As we see i am using mm session save handler which stands for Shared Memory. From php.net: To use shared memory allocation (mm) for session storage configure PHP –with-mm[=DIR] .

    we probably need to install php Shared Memory extension to use this kind of session handler: http://php.net/manua…/book.shmop.php
    Default php session handler is file handler which store your session in files on file system. This handler do not need any additional extension.

    see more about sessions:
