When you try to update a banner from the listing, change the image or something else and click on Update button. A successful message is shown, but the row is replaced by 0!
Why is that?
Also there is no way of managing Ad Groups. If by mistake you create a group, you can never delete it.
Regarding the same I found that we are storing group names directly in the column in the “bannerize” table, instead of creating another table and storing the name and id of the group in that table and referencing the id in the “bannerize” table. Why keep redundant values in all rows?
