After transferring to a new host I get errors

I followed the tutorial for moving from one host to another https://www.zen-cart.com/tutorials/index.php?article=100. I got the database imported and all the files uploaded. Admin seems to be working ok. But when I try to go to the home page I get the following:

] . " set user_email='" . $email_address . "' where user_email = '" . $old_email . "'"; $phpbb_users = $this->db_phpbb->Execute($sql); } function phpbb_change_nick($old_nick, $new_nick) { // before utilizing this function, we should do an MD5 password validation first if ($this->phpBB['installed'] != true || !zen_not_null($nick) || $nick == '') return false; $sql = "update " . $this->phpBB['users_table'] . " set username='" . $new_nick . "' where username = '" . $old_nick . "'"; $phpbb_users = $this->db_phpbb->Execute($sql); } } ?>

I managed to get a couple of the errors fixed. Here is what is showing now:

] . " set user_email='" . $email_address . "' where user_email = '" . $old_email . "'"; $phpbb_users = $this->db_phpbb->Execute($sql); } function phpbb_change_nick($old_nick, $new_nick) { // before utilizing this function, we should do an MD5 password validation first if ($this->phpBB['installed'] != true || !zen_not_null($nick) || $nick == '') return false; $sql = "update " . $this->phpBB['users_table'] .

try opening this file
/home/xxxx/public_html/includes/classes/class.phpbb.php and going to the very bottom put cursor directly after the last ?> and hit delete about 10 times save and re-upload

Merlinpa1969:

try opening this file

Ok, I did that but no change. Just looking at the file, it doesnt look exploded or anything. But I did notice this section was not parsed by my php editor beginning on line 249 near the end of the file:

?>] . " set user_email='" . $email_address . "'
where user_email = '" . $old_email . "'";
$phpbb_users = $this->db_phpbb->Execute($sql);
}

function phpbb_change_nick($old_nick, $new_nick) {
// before utilizing this function, we should do an MD5 password validation first
  if ($this->phpBB['installed'] != true || !zen_not_null($nick) || $nick == '') return false;
    $sql = "update " . $this->phpBB['users_table'] . " set username='" . $new_nick . "'
            where username = '" . $old_nick . "'";
    $phpbb_users = $this->db_phpbb->Execute($sql);
}

}
?>

Also, Now I'm getting another related error on the home page which is this:

Warning: Cannot modify header information - headers already sent by (output started at /home/XXXXX/public_html/includes/classes/class.phpbb.php:256) in /home/XXXXX/public_html/includes/init_includes/init_templates.php on line 78

Thanks for your help. It's much appreciated.

FIXED IT! I just copied the old file again from the old installation to the new one. That last part of code had gotten corrupted in the ftp. Everything looks great now!

Thanks!
