    hello dear all

    some more investigations:

    This error means that our 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 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:
    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 some more infos rearding the sessions:

    well - now i think that i have to rework the configuration

    Yes, either install shmop support, or change the session handler before any session work happens:

    PHP Code:
    ini_set("session.save_handler""files"); //use the filesystem to store session data
