The behaviour depends on how fonts were applied within the article: - **Content using the project-level default font** will automatically update when the project font is changed. - **Content with manually applied fonts** will retain those fonts and will not be affected by changes to the project-level font. In other words, default fonts are dynamic and inherit changes from the project settings, while manually applied fonts are static and continue to render using the selected font. #### How are unsupported fonts handled in Document360? If a font is no longer supported by Document360, content may still render correctly if the font is available on the end user's device. If the font is not available, the browser will automatically use a suitable fallback font to ensure the content remains readable. **Why is a contributor visible in Article Info but not in Manage Contributors?** This happens when the user account is deactivated in the project. Deactivated users are removed from the Manage Contributors list but their historical contributions are still shown in Article Info and analytics. To completely remove the contributor from all views, the user **must be permanently deleted from the project.** Deactivation only retains past contribution data while hiding the user from active contributor lists. ### **Email Links (mailto:) in Document360 Articles Not Opening Default Email Client** #### Error When clicking an email hyperlink (mailto: link) within a Document360 article, a blank browser page is displayed instead of launching an email application or creating a new email draft. This issue typically occurs when the MAILTO protocol is not associated with a default email application on the user's device. Since email links rely on the operating system and browser to identify and launch the configured email client, the browser may open a blank page if no application is assigned to handle the protocol. Example: `mailto:username@test.com` #### Resolution Configure a default email application on the device and associate it with the MAILTO protocol. 1. Open **Settings** on your Windows device. 2. Navigate to **Apps** > **Default Apps**. 3. Search for **Email** and select your preferred email application (for example, Microsoft Outlook or Windows Mail). 4. In **Default Apps**, select **Choose defaults by protocol**. 5. Locate the **MAILTO** protocol and assign the same email application as its default handler. After completing the configuration, return to the Document360 article and click the email link. The configured email application should launch and open a new email draft addressed to the specified recipient. ### **"This article has no listed contributor. Please assign one."** This warning appears in the editor when no contributors are assigned to an article. This typically happens when the original creator's account has been deleted, removing their association with the article. To resolve: 1. Open the article in the knowledge base portal. 2. Click the **Article information** () icon in the article header. 3. In the **Contributors** section, confirm no contributors are listed. 4. Click **Manage** to open the contributor management interface. 5. Search for and select the appropriate contributors. Click the **Add as contributor** () icon next to their names. 6. Confirm the contributor's name now appears in the Contributors section and the warning is no longer displayed. ![Article information panel showing the no contributor warning](https://cdn.document360.io/860f9f88-412e-4570-8222-d5bf2f4b7dd1/Images/Documentation/image-1774950960983.png)
