don't take it serious / seriously

Hi, I googled before I came here to ask, but didn't get a clear answer.

I often say 'Don't take it serious', but I also know many people say 'Don't take it seriously'

The reason is I think 'serious' as "an object complement" of the object "it", whereas others consider 'seriously' as "an adverb" for the verb "take" in the sentence. I think they both are considerable. (maybe it depends on whether you speak AE or BrE?, I don't know.)

Another example would be; Take it easy vs. Take it easily

Ok, lets say they are all ok grammatically, but what about when it's in a passive sentence like this?

The feedback needs to be taken seriously.

I would definitely use the former one (seriously=adverb). But, would the latter one possibly be correct by any chance (Assuming you think 'Don't take it seriously' and 'Don't take it serious' are both correct)?
