I have 2 sub domains:
https://music.harmonicatabs.net/
https://reviews.harmonicatabs.net/

With https://music.harmonicatabs.net/, it dont show ads
With https://reviews.harmonicatabs.net/, It makes my site not function properly. When I try to create and edit ads on the website, I keep losing connection!

How can i fix it?

Ads are not enabled on the music subdomain and that appears to be intentional. It's not possible to display ads next to lists of audio tracks.

What is not working correctly with your site on the reviews subdomain? Is it just editing the ads or something different?

You can use the Chrome extension to view the ad placeholders on your site. It's also possible to edit the placeholders through the placeholder table in your Ezoic dashboard (-> Ezoic Ads -> Ad Positions -> Placeholders / Generated Placeholders).

hoangnguyen I'm not seeing any ads being inserted into the element you showed in the screenshot. However, I did see our Universal Player being added in that element. The Universal Player requires its own CSS exclusions which you can add or import from your ad exclusions here: https://pubdash.ezoic.com/humix/site/disable-locations

I've already imported the ad exclusions to the Universal Player on your behalf, so clear the cache and you should be good to go.

If you continue facing issues let us know, and please elaborate exactly where ads are breaking the CSS, with further screenshots and details, and we can look into it.
