Not knowing the real nature of things is the cause of clinging after death.
Again: Ignorance is the cause of clinging after death.
Again: Not knowing the truth is the cause of clinging after death.
All three are the same: not knowing the real nature of things , ignorance and not knowing the truth.
All are not knowing ... ignorance ... not being able to discern lies from truths ... thinking "this is so and so" when it is not so and so ...
That being said, what was said is the cause of clinging after death.

The previous life, mind&mind factors&forms, is pakatūpanissaya-cause of the after-life.
The previous kamma is nānakkhanikkakamma-cause of the after-life.
The previous life is ārammaṇa-cause of the after-life.
All above is clinging aggregate.
