I did "test text" and it shows that but not banners from adsense

If it works with the text or images then something wrong with your code, please check the code to make sure everything is correct. 

I have also problem with adsense. It is working with other plugins but not with with wpdiscuz AdsManager addon.

Kindly advice

Please try to check by using some text or image to make sure that everything works as expected. Also please make sure you switch on the text mode before checking: See the screenshot below:

I created a new advertising in Ad Managerwith the Adsense code. I created a new Ad Banner with the setting: comments form bottem, to see what happens(hopefully the adds will be at the bottem of the page).i linked in aAd manager at the banner column the by me created banner, created a start date but nothing shows up.

Any idea what i am doing wrong?

Thank you.

many thanks for the reply. is there a printscreen availble so i can see how to do that?

You just need to navigate to the Dashboard > Comments > Ad Manager > admin page, click on the "Add New button" then put the JS code in the post content. Please see the screenshot below:

Second, is it also possible to put Admanager at a different location, lets say at the bottem of the page?

wpDiscuz Ads Manager is a light and powerful advertisement management system that allows you to add ads in the comment area (after and before comment form, after and before comment list, after and before comments). You can display adverts in comment form and on the comment list. There are many locations and the ability to create ad banners with different displaying logics.
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. See the screenshot below:
