Censored data - rejecting initial value

I am modelling left censored data. Following Stan’s manual, I have integrated out censored values in the model block. However, testing the code with 1 chain produced the following error:

Chain 1: Rejecting initial value:
Chain 1:   Log probability evaluates to log(0), i.e. negative infinity.
Chain 1:   Stan can't start sampling from this initial value.

but sampling still did complete.
My question is, can the result be trusted with this error?
