Description and Message
Hi,
my portal is still working fine.
After the upgrade to 3.0.4 I can't acces my portal config in the ACP any more.

I get this error:

hpEx", 'i=portal&mode=links&action=add'); return ''.$user->lang['PORTAL_LINK_ADD'].''; } } function utf_unserialize($serial_str) { $out = preg_replace('!s:(\d+):"(.*?)";!se', "'s:'.strlen('$2').':\"$2\";'", $serial_str ); return unserialize($out); } ?>on utf_unserialize($serial_str) { $out = preg_replace('!s:(\d+):"(.*?)";!se', "'s:'.strlen('$2').':\"$2\";'", $serial_str ); return unserialize($out); } ?>[phpBB Debug] PHP Notice: in file /adm/index.php on line 150: Cannot modify header information - headers already sent by (output started at /includes/acp/acp_portal.php:488)

Any idea how to solve this issue?

Take a original adm/index.php from the phpBB3 package and redo the portal changes as stated in the install.xml.
