I have the problem with 188.8.131.52, too. Mine is running on a STRATO VServer. I have optimized with APC and other stuff.
Sometimes moneybookers payment works normally, sometimes not. Might be a performance issue. Seems to be timeout at moneybookers. After clicking on Place Order it hangs and never finishes.
Paypal working without any problems…
Pls, help.... How can we check where the problems come from. Is there any issue reported already? Whom to contact.... Thanks
