# My mobile site shows a blank page

> A menu item or campaign URL loads blank because the destination site blocks framing; switch it to open in a new tab or update the site's CSP.

The destination site is refusing to load inside the mobile site. Menu item URLs and campaign URLs open in an embedded frame; when the destination's `content-security-policy` does not allow your platform domain as a frame ancestor, the browser shows a blank page.

## Immediate fix

Open the URL in a new tab instead of a frame.

1. For a menu item: under **Platform Admin → Enabled Features → Mobile Store Sites**, open the template and the menu item, select **Open in New Tab**, select **Save**, then **Save Changes**.
2. For a triggered campaign: on the campaign's **Creative → Call to Action** tab, switch **Open Campaign URL in New Tab** on and select **Save Changes**. Turn off any pop-up message first under **Interaction Settings**. See [Create a call to action for on-rotation campaigns](https://personalisationhub.com/support-centre/mobile-store-sites/create-a-call-to-action-for-on-rotation-campaigns/).

## Longer-term fix

Ask the destination site's webmaster to allow your platform domain in its content security policy, for example:

```
content-security-policy: frame-ancestors 'self' *.yourdomain.com;
```

If the platform runs on your organisation's primary domain, your own sites are likely to allow it already.
