Element 'referenceContainer', attribute 'after': The attribute 'after' is not allowed.

Am Getting this error after upgrading 2.1 to 2.2, where am sure its coming from the front-end design because when i switched to default theme, there is no errors at all.

But i cant narrow down where is the error occurred ? as well how to solve such error ?
