My 1.3.7.1 store suddenly don´t register purchases made by customers.

[FastLeopard]

Hi:

I run the Zen Cart 1.3.7.1 version since 2007, and I´ve never had any problems. My host is Lunarpages.

1) Yesterday a client made a purchase in my zencart, and I received her payment with paypal. Paypal sent me an email saying I was paid 32.50", for that purchase.

2) But the problem is that neither paypal, nor my zencart tell me what did the client buy, so I don´t know what product I have to ship her.



Please:

¿ What could cause this error?
