email piping error

[Franklymydear]

Hi, folks - first post here and I am seeking assistance - :o - I either need to know how to define the function correctly - or is it a cPanel issue
(my developer suggested this "Here is the issue, lately Cpanel was updated. now the host has to manually install the imap module for php.)Send your host the following information:
"/scripts/easyapache , option 6 , PHP Modules: ensure "IMAP" is ticked." )

The software checks for email tickets using email piping and I'm getting an error

Fatal error: Call to undefined function: imap_open() in /home/XXXXXX/public_html/help/receive.php on line 161

history - it did used to work -
My knowledge (not much)
Developer (fast asleep on the other side of the world)
Urgent? 'fraid so

CPanel upgraded - and hasn't worked since.

Code (it's not the whole file, but might be enough to give you a clue):

$query = "SELECT * FROM mail_accounts";
$mail_accounts = mysql_query($query);
while ($mails = mysql_fetch_array($mail_accounts))
{
$receive_server = $mail_servers[$mails["ms_id"]];
$r_login = $mails["login"];
$r_password = $mails["passwd"];
if ($mail_servers_type[$mails["ms_id"]] == "p") $receive_server .= "/pop3:110";
else $receive_server .= ":143";

    if ($mbox = imap_open("\{$receive_server}", $r_login, $r_password))
    {
            $count = imap_num_msg($mbox);
            for ($j = 1; $j <= $count; $j++)
            {
                    $header = imap_headerinfo($mbox, $j);
                    $email = $header -> from[0] -> mailbox . "@" . $header -> from[0] -> host;

                    $date = trim(preg_replace("/[^,]*,/", "", $date));
