Certificate template doesn't work

guren1290 · January 30, 2025, 3:30pm

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) , 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.

```
  <div>*
```
```
  <font color="#000000" </font>*
```

  	<h2>${accomplishment_banner_opening}</h2>*

  	<p class="message-copy copy copy-base emphasized">${accomplishment_banner_congrats}</p>*

```
  	<div class="message-actions">*
```

  		<button class="inverse" id="action-print-view">*

```
  			${_("Print Certificate")}*
```
```
  		</button>*
```
```
  	</div>*
```
```
  </font>*
```
```
  </div>*
```

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.

Thank you for responding to my question. Please help me figure it out, I’m new to this

You are running Tutor as root. This is strongly not recommended. If you are doing this in order to access the Docker daemon, you should instead add your user to the ‘docker’ group. (see Post-installation steps | Docker Docs)

Hello @guren1290

I’m pretty sure the problem is “${_(“Print Certificate”)}*” but if you want you can use this template:

cert_template.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
