Hi Thomas,
That’s interesting. I’m not using Pro, but when I added the ID to the AdSense account field and hit save (Connect didn’t seem to be working at the time), the admin-ajax call response would have the JSON response but above it, the script tag containing the AdSense fragment would be inserted as well.
Clearing the Adsense account field and re-saving resolved the issue, and I attempted this several times trying to determine what was wrong. I even went so far as disabling all other plugins aside from Unyson (the modules were triggering admin-ajax which is how I was reproducing the problem) and the problem still persisted.
In the end, after restoring my other plugins, I deleted and reinstalled Advanced Ads and the problem seems to have gone away.
For reference, in case this crops up again, are you able to advise which hooks/filters output the Adsense fragment? I can then try to diagnose whether there may be a conflict.
Thanks
