Ooooh, that's bad.  According to the error message, it looks as
though your /tmp filesystem has somehow been mounted "read only",
such that PHP is unable to write session files to the directory.
But if /tmp truly is mounted read-only, then I suspect a lot more
is breaking on the system than just PmWiki.

One workaround might be to create a directory somewhere else for
PHP to store its session files (give the directory 777 permissions),
and then tell PHP to use that directory for storing session data:

    session_save_path('/path/to/session/dir');
