Hi @ljpp,
Sorry for the late response. To make this work with AdSense, you need to set both of these (the naming is confusing):
adsense_nth_post_code— this is not an ad unit code; it’s the interval: the number of posts between ads (set to 3 = an ad after every 3rd post).adsense_post_bottom_code— the actual AdSense unit number for the between-posts slot, plus a size inadsense_post_bottom_ad_sizes(mobile:adsense_mobile_post_bottom_code+adsense_mobile_post_bottom_ad_size).
These only work if adsense_publisher_code (your publisher ID) is filled — that’s the setting that enables AdSense.
If nothing shows: check that the viewing user isn’t in the adsense_exclude_groups (staff/admins are excluded by default).
Let me know if you have any other questions
