Hi, I have a problem on automatic certificate generation issue on Maple after upgrading from Lilac (with Tutor installation method). On my previous Lilac, I can enabled a course automatic certificate generation by set the `early_no_info` value ([18.5. Ending a Course — Building and Running an Open edX Course documentation](https://edx.readthedocs.io/projects/open-edx-building-and-running-a-course/en/latest/student_progress/checking_student_progress.html#allow-learners-to-download-certificates)) and somehow this **Certificates Display Behavior** were disappear from Maple’s Course Advanced Settings. Secondly I then enabled `certificates.auto_certificate_generation` waffle switch on Django Admin. Now if a learner go to Progress page it couldn’t be opened and show “There was an error loading this course.” error.

But, no certificate download link on this page when a learner has passed the exam. I know there are some various [bugs fixed and updates of Certificate on Maple](https://edx.readthedocs.io/projects/open-edx-release-notes/en/latest/maple.html#certificates) version but since I’m new and have no more deep knowledge in this area. I really appreciate if someone could assist me on this issue. Thank you in advance. [bayu] ---

Hi @Zia_Fazal it’s solved! By enabling persistent grades via Django admin. But the link for Certificate download is still not appear. ![nocertdownload](https://us1.discourse-cdn.com/flex020/uploads/openedx/original/2X/6/6555caf7284d89dc501a050e2178e65462652ded.jpeg) Thank you so much! ---

Hi, I will update and summarize what I’ve done so far (enable automatic certificate generation and allow learner to download early certificate) Lilac: 1. Enabled `certificates.auto_certificate_generation` waffle switch on Django Admin 2. Set **Certificates Display Behavior** to `"early_no_info"` Upgrade to Maple: 1. Error log regarding generate course certificate which will affect page loading error is fixed by enabling persistent grades on Django admin. 2. No “View Certificate” button on Progress’ learner page 3. Problem #2 is fixed by adding the course ID to certificate generation course setting on Django Admin (/admin/certificates/certificategenerationcoursesetting). The result is a “Request Certificate” button appears on Progress page. 4. “Request Certificate” button is still not up to my expectations where in lilac the “View Certificate” button appears. Hence no more step for learner to download his/her certificate. 5. I found that there is no **Certificates Display Behavior** on Maple course’s Advanced Settings, but now that “option” appears on Course Details page (Settings \> Schedule & Details) with the default value `end`. 6. I know that to allow learner to download early certificates is by set the Certificate Display Behavior to `early_no_info` on Certificates Display Behavior setting. 7. By doing the trick to change the `end` value to `early_no_info` on Course Details page fix #4 issue. The “Request Certificate” button is not show up replace with “View Certificate”. ![Certificates Display Behavior on Maple](https://us1.discourse-cdn.com/flex020/uploads/openedx/original/2X/4/4b7f782898e384bba4a26c32ef028ec8f6485525.jpeg) Questions: 1. Is there any steps I missed? 2. Can these steps (“tricky”) be a workable solution at this time? Since the Maple documentation regarding this subject is still refer to Lilac. Regards, ---

What version are you using? If the course created on Lilac and you upgrade to Maple, it will not display. Try to create a new one on Maple. Thanks, ---

I confirm that even importing an old course doesn’t work. How do we handle courses that have been existing for a while, for example on Koa in Native, when we will switch to Tutor and Maple? We have long running courses that deliver certificates either auto-generated or at the end. Is there a migration command we need to run? We can’t assume a course will end before our move to Tutor. That would be a logistic nightmare… ---

Hello Maria, I hadn’t seen that PR and it definitely looks like the same problem I encountered recently. Nice catch. Thanks for forwarding this to me. We had already decided to turn on Persistent Grades in the future (definitely before we move from Koa under Native to Maple or Nutmeg under Tutor), but it is great to understand what was going on. Thank you.
