Hello everyone, nice to greet you. I would like you to help me with this issue in the Sumac version, since I cannot add custom templates to the certificates. In my lms.env.yml file, I have already added the following: `FEATURES:` `CERTIFICATES_HTML_VIEW: true` `CUSTOM_CERTIFICATE_TEMPLATES_ENABLED: true` Also, in /admin I have already enabled the custom certificate with the course key, but nothing, I can’t manage to make the custom certificate appear. Could you please help me? ![Screenshot 2025-12-11 011259](https://us1.discourse-cdn.com/flex020/uploads/openedx/original/2X/9/97fff1aa65494a3008c040dbd9b83d47ce29b21d.png) ![Screenshot 2025-12-11 011125](https://us1.discourse-cdn.com/flex020/uploads/openedx/original/2X/d/d6fa9b4075676a8e9c8553af4e7dcee53e69a18e.png) ---

HI try 1. Create the Tutor plugin file at: [Creating a Tutor plugin — Tutor documentation](https://docs.tutor.edly.io/tutorials/plugin.html) docs tutor ~/.local/share/tutor-plugins/custom\_certificate.yml Add the following content: ```auto name: custom_certificate version: 0.1.0 patches: common-env-features: | CUSTOM_CERTIFICATE_TEMPLATES_ENABLED: true ORGANIZATIONS_APP: true CERTIFICATES_HTML_VIEW: true ``` 1. Enable the plugin: tutor plugins enable custom\_certificate tutor config save tutor local restart 2. Enable certificate mode for the course: Go to /admin/course\_modes/coursemode/add Create a Course Mode with: - Mode: honor - Certificate enabled: ✓ 1. Create a custom certificate template: Go to /admin/certificates/certificatetemplate/add Create your template and assign it to the course. Do not forget to select the **Organization** that matches your course. 2. Test: Enroll a test learner → complete the course → generate certificate. If configuration is correct, the custom template will be used. work for me ---

**Nothing, I added it just as you mentioned, but the certificate still uses the same one. Can it still be done in Sumac?** ![image](https://us1.discourse-cdn.com/flex020/uploads/openedx/original/2X/7/70c8ef5b25df6df9eca8ad31eda412a52e17d17f.png) ---

By default, Open edX grabs the template from here: > edx-platform/lms/static/templates/certificates/valid.html. Just tweak that file, restart LMS (like tutor local stop lms && tutor local start lms -d), and boom, it should pick up your changes. If you’re running a custom theme like Tutor Indigo, it’s better to override the template. Create the file in your theme’s template directory: > /templates/certificates/valid.html For more details on Indigo theming, check out the repo: [[GitHub - overhangio/tutor-indigo: An elegant, customizable theme for Open edX](https://github.com/overhangio/tutor-indigo?tab=readme-ov-file#customization)). ---
