# The widget doesn't show up
_Category: Troubleshooting_
When the widget's button doesn't appear on your site, one of these causes is almost always behind it. Start at the top.
Your browser's console often names the problem. In most browsers, right-click the page, choose **Inspect**, then open the **Console** tab and reload the page.
## Your website isn't in Embedding origins
This is the most common cause. The widget runs only on websites you've approved, and while the list is empty it's blocked everywhere. The console shows **"Parent domain is not in the allowed list."** followed by the domain the widget found.

- Ports don't matter, so `localhost` also covers `localhost:9090` while you test on your own computer.
- Add as many domains as you need. You'll find the same list under **Embeddables** → **Widget** → **Configuration**.
## The snippet isn't running on the page
To check, type `hcOptions` in the console and press Enter. If you see your `app_id`, the snippet ran. If the console says `hcOptions` is not defined, it didn't.
1. Copy the snippet again: click the gear icon, then **Embeddables**, and under **Installation** click **Copy**.
2. Paste it right before the closing ` ` tag of the page. The snippet adds the widget to the page body, so placed in the `
