where do you try to run Abantecart? remote host or local?
Looks like your server can not start session.
Please check manual http://php.net/manual/en/function.session-start.php

hello
my host cpanel
please help me to start

[abolabo]

it's a hosting provider misconfiguration issue.
They forgot to allow writing for /tmp directory for them users.
To solve issues needs to add directive

Code Select Expand

session.save_path=/your_tmp_directory into file public_html/php.ini
In this case /your_tmp_directory was /home/user_{ID}/tmp
