Classifieds listed , turns to "draft" after specific time period

classifieds are published as per normal.

After a specific amount of time, they unpublish and become

“Drafts ”

FYI :

Taxonomy

I have deleted the “expiry” taxonomy as there is no need for it.

( could this be the problem ?)

Classified status options

I have only enabled ” publish ” and disabled “Pending review” and

” Draft”

Please assist urgently, as published adverts are reverting to drafts.

Please additionally also check test site as well http://www.crestviewvet.co.za/wp

for the problem.
