Really appreciate your help on this.
The missing < in <?php was a copying mistake, it's there...
I've checked the phpinfo() file but there's no section on Sessions,
'--enable-session=shared' in the Configure Command section
Additional .ini files parsed /etc/php7/20_session.ini
in the standard section....
session.trans_sid_hosts no value no value
int the Environment section ...
I have removed and re-installed php7-mod-session, rebooted, and performed an uhttpd restart ... to no avail, error message still there when opening page...
Maybe removing all PHP7 packages and re-installing will resolve this, otherwise ??
