Session ID attached twice to Callback URL - WHY ?

[spaceflo]

Hi,

 

I have located an error that caused several orders with creditcard payments not to be registered or listed in the shop while the payment went through successfully but the customer still got an error code.

 

On the page "checkout_confirmation" in the source code I found the following :

 

******

<input type="hidden" name="MC_callback"

value="spaceflori.com/checkout_process.php?osCsid=e2e96a0942e9eb03852fab7738

c1e463?osCsid=e2e96a0942e9eb03852fab7738c1e463">

******

 

As you can see the session ID is attached TWICE to the callback URL.

This only happens with my creditcard module, all others work fine.

 

Can anybody enlighten me how to correct this problem and where I have to edit which file ?

I'm pretty new to this, so any detailed info would be most appreciated.

 

thank you very much in advance

Florian
