I always thought that the universe is expanding faster than the speed of light.
Am i wrong, or is that only during the proposed period of "inflation" in the early universe.

Your second description is correct, i.e. speed of expansion was much greater than the speed of light during inflation.

While that is correct it is also true that in a large enough universe any homogeneous expansion will mean that a region far enough away will be receeding from us at faster than the speed of light.
However this does not violate SR because it is space-time itself that is expanding, not the motion of objects within space-time, they are simply being carried along with that cosmological expansion.
