Display Ads won’t show up

Hello!

No matter what I tried, ads won’t show up.

I set up the mentionned test on the webseite of Ad inserter and added the code <p></p>
into posts before content.

In the code the application itself is seen, but the TEST code isn’t.

I tried to deactivate all plugins except ad inserter, but even then, the issue continued.
