I got the error like this

Warning: Unknown(): Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0
and this
Parse error: parse error, unexpected T_IF in /home/vuonongb/public_html/member.php on line 381

any suggestion what I should do ?

How about some inforfmation on what you are trying to run?

the site I run all php file and it was working fine form the old server, when I move to this server the the error occured don't know what is going on.
my guess is some thing due to the php.ini but not really sure
