I spend a year in Liberia in 2001 and I must say that human sacrifices were common things but noot accepted.
The population was against but, as described into Stephen Ellis book, it's the main counter power there. Liberia central State has been fighting against it basically since it's creation.

What is really disturbing in Liberia is that the symbolism into Christian religion has been used to legitimate canibal practices.

But I would also add this
1) it always has been a limited thing.
2) According too Ellis, Taylor deregulated the practice t make it common, accessible t all. And that's what sunked Liberia in a place that even the devil forgot (cf Liberians).
3) Population is against it and the deregulatioon of it has been one of the core reasons Liberia peace has been achieved through an in depth societal change: they elected a women!
