FAQ
The PDF Export feature was removed due to security vulnerabilities related to the use of a headless Chromium instance. Plans are in place to re-add this feature safely, but it is not expected until HedgeDoc 2.1 or later.
No, running multiple instances of HedgeDoc on the same database is not recommended. The server process is not entirely stateless, which can result in missing or broken content for users. Instead, use a high-level orchestrator to ensure only one instance is running at a time.
Many servers block embedding due to security settings like the X-Frame-Options header, which is often set to SAMEORIGIN. To embed a PDF, the hosting server must either omit this header or explicitly allow your HedgeDoc instance's URI in an ALLOW-FROM statement.
Embedding HedgeDoc notes via iframes is disabled by default for security reasons. To enable it, ensure your instance is served over HTTPS, set CMD_COOKIE_POLICY to 'none', and enable CMD_CSP_ALLOW_FRAMING. Refer to the configuration docs for details.
This issue is often caused by a missing or incorrect CMD_DOMAIN configuration or reverse proxy setup. Check the reverse proxy documentation and ensure CMD_PROTOCOL_USESSL is set to true if using HTTPS.
Older versions of HedgeDoc had migration bugs. Refer to the Troubleshooting Migrations guide for steps to resolve this issue, as migrations may not have been properly recorded.
If the interface appears broken, HedgeDoc may not be able to find asset files like images or stylesheets. Verify the CMD_DOMAIN, CMD_PROTOCOL_USESSL, and CMD_URL_ADDPORT settings (or their environment variable equivalents) and check the reverse proxy guide for configuration help.
