求救：snort安装时的acid显示问题

wstry

我在linux下安装了libpcap+snort+mysql+apache+php+acid+adodb+phplot
安装后snort可以正常运行，而且数据也可以写到mysql数据库里，但是用acid查看时可以显示标题，正文总是出现错误：

Fatal error: Cannot redeclare unixdate() in

/usr/local/apache/htdocs/adodb/adodb.inc.php on line 1219

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


请问这是怎么回事？
谢谢！！！
