Finishing the order - losing connection

[KlyX]

Hi guys

 

I installed WHMCS revently and I'm still on the way to configure everything properly. What I found out in my first test: when a customer or non-customer finishes his order and Checkout he should get to the page with the order number. Instead, after a while firefox shows "no connetion to the server". If I reload the page I get the page I wanted, including order number and everything seems fine.

 

But it's definetly not good if this happens through a real order .

The server itself was up all the time and I can reproduce the phenomenon every single time.

I tried to use SSL and no SSL... same here...

 

Maybe you can help?

 

Thanks a lot
