Potential work around for some people:
I deleted the field that was saying “Approved” and recreated it, now I don’t have the issue any more, though that of course results in data loss.
Also, even when I get the approvals column working I find that every time a new entry is added all previous entries are hidden in the directory. The Entries UI still show ticks for the approved ones and I can re-approve them by unapproving them then reapproving them but it is a manual process as I don’t have the bulk options either.
@pvraman:
I have experienced the same issue as @karmicbliss so I can supply the request details.
I applied the workaround as detailed and it fixed the issue with approvals (showed the approval column in the Entries view and worked correctly with showing/hiding stuff).
The Approved field ID is 11, the “Suburb” field ID (the one I see “Approved” in) is 10.
/wp-admin/admin.php?page=gf_entries&id=8&sort=10
Hope that helps to diagnose the problem.
