could you please leave some screenshot of Ads and Banners settings? Have you seen the difference of these two items? Also have you used these buttons for deleting Ads cache:
I have attached some screen shots. I have used tried both resets as well as using a second computer to be sure it wasn't IE or Edge Cashe.
I am sending you my credentials for another post if that helps and I am making your users an admin. I look forward to learning and documenting what I have done wrong so I can train my colleagues the correct process.
It works fine, you've forgotten to attach the new Add to a Banner (we call banner the location of ad):
We've created all locations (banners) in Comments > Ad Banners admin page, you just need to choose one of them when creating a new Ad in Ad Manager admin page.
I have written up what I understand the process to be. (in case I ever have to do it or for anyone else you might be looking.
1. First in the Ad Banner section you remove incorrectly the "Banners" what I had done . (because they where not banner locations)
2. In the Ad Banner section: when referencing a New Banner it is meaning banner locations and only banner locations. Not the actual Banners.
So, next in the Ad Banner section: You created "New Banners" that represent the banner locations in the Comments sections. Screen shot below.
3. Then, in the Ad Manger: You created the New Banner with the actual content and most importantly assigned the location as you demonstrated in your screen shot above.
Please let me know if I missed a step. Thank you for the handholding.
