Worldpay need help please: Our systems have detected that your callback has failed

[bridge32]

Hi all, well i read pretty much of these 60 pages!
My problem i only have with this mod, is that it times out?
Here is the email i received:

Our systems have detected that your callback has failed.

This callback failure means we were unable to pass information
to your server about the following transaction:

Transaction ID: 2064097426
Cart ID: b02c5f86f8941dac71bf2f3cbb7598b0
Installation ID: XXXXXX

Error reported: Callback to: http://www.cakekraft.co.uk/index.php...e=wp_callback: failed CAUSED BY Read timed out
Server Reference: mm2imsps4p:callbackFailureEmail-130046:MerchReq-377-42

Also, if you usually return a response page for us to display to the Shopper
within the time allowed (1 minute), this will not have been displayed.

RBS WorldPay will have displayed to the Shopper the response page file
(resultY.html or resultC.html) held for your installation on the RBS WorldPay
server. This will be your own custom version, if you have supplied one, or,
if not, the RBS WorldPay default version.

I have also placed this in the support forum but thought i might get more response here.
Please can someone help, as people are placing orders and it's not showing in Zencart.
Thank You.

Ok i have managed to fix this now, by reading all 66 pages of the support thread
Now i just need some help with 1 thing...
When the customer cancels, or pays, and are directed back to my site, the page does not display correctly, it's all messed up.
I know it's a css thing by reading the other posts, but can someone clarify if i get an ssl cert will this problem be rectified?
Thanks
Nic.
