Symptom
When you open a quote in Preview mode inside Quotivity, the layout looks broken — fonts, colors, spacing, and other styling are missing. However, once the quote is published, it displays correctly.
Cause
This happens because of a setting in your HubSpot account called Default file hosting location, found under Settings > Website > Pages > SEO & Crawlers.
Quote templates pull in supporting files (like stylesheets) from wherever HubSpot is configured to host your uploaded files. If this setting points to your company's own custom domain instead of the default HubSpot CDN, your browser's Content Security Policy (CSP) may block those files from loading in Preview mode — because the custom domain isn't on the list of sources your CSP allows.
Once a quote is published, it's served through a URL that's already trusted, so the styling loads correctly and the issue isn't visible. Preview mode uses a different loading context, which is why the problem only shows up there.
Fix
Update your default file hosting location
- In HubSpot, go to Settings > Website > Pages > SEO & Crawlers.
- Locate the Default file hosting location setting.
- Change it from your custom domain to the HubSpot CDN option.
- Save your changes.
- Return to Quotivity and re-open the quote in Preview mode to confirm the formatting now displays correctly.
This change only affects where newly referenced files are hosted by default. It will not impact your existing published web pages or landing pages.
