You need to wrap the “ad-header” element with your custom div element and give it a class, then type this class name inside the plugin’s settings.
e.g.
<div class="ban-notice"> //use any class name you want
<div class="row ad" id="ad-header">
//some adcode
</div>
</div>
Now, go to the plugin’s settings and type in the class name that you used “ban-notice” and use that same class name to wrap all other ads.
