I have a certificate template registered in Django, when it is active, an error appears when generating the certificate ([https://us1.discourse-cdn.com/flex020/uploads/openedx/original/2X/6/6f4588ec74369174ad33623805c382dab28c7e09.png](https://us1.discourse-cdn.com/flex020/uploads/openedx/original/2X/6/6f4588ec74369174ad33623805c382dab28c7e09.png)) , if I disable the certificate template, a standard certificate is generated. Tell me, what could be the matter? If I remove this fragment with the print button from the template, the certificate is generated normally. I have a tutor 19. - ```

Hi @guren1290, welcome to the community! Please check the logs in the LMS, this will give you a hint of what is wrong in the template. ---

Hello @guren1290 I’m pretty sure the problem is “${\_(“Print Certificate”)}\*” but if you want you can use this template: [cert\_template.txt](https://discuss.openedx.org/uploads/short-url/xFnirHCm8ZXEIsefHRkbwJH6tbU.txt) (7.1 KB) Also make sure the course start and end dates are set correctly if your course pace is set to “Instructor Pace” (in my experience I recommend using “self-paced” and enabling certificate auto-generation). good luck, rax ---

Hello, could you help me with the configuration? I already added the CUSTOM\_CERTIFICATE\_TEMPLATES\_ENABLED CERTIFICATES\_HTML\_VIEW I also added the templates in admin/certificate/certificate templates, but it doesn’t apply the customization. Did you do any extra step? I still have Tutor V19
