I have updated the version of ANKI and, when I go to study my multiple choice notes (1 valid answer among 4 alternatives), the message “The front of this card is blank” appears.
What do I have to do to get it working again? I have several hundred cards and I wouldn’t want to lose them.
Thank you.
I can’t answer you in Spanish, unfortunately. It sounds like you need to add a Field Replacement back to your Card template. Manual de Anki
Thanks for your answer, but:
- The online Anki Manual doesn’t fit to the last version 23.12.1
- I don’t know programming in HTML
When you see the message that the front part of the card is blank, press the “e” key (for Edit), and then in the window that pops up, click on the Cards… button.
Another window will pop up and will show you the “Front template”. What text is visible there?
Thanks! This is the code:
{{#Title}}
{{Title}}
{{/Title}}{{#Question}}
{{Question}}
{{/Question}}{{Answers}}
{{QType (0=kprim,1=mc,2=sc)}}
When you hit the “e” key, the first window that popped up was the “Edit Current” window. It should contain fields including Title, Question, Answers. Are all of those fields blank?
If this is really not a valid note, and it has no good information in any of its fields, you can press the “m” key when you see “The front of this card is blank” and then select “Delete Note” from the popup menu that appears.
You can also select Tools / Empty Cards… from the menu, and that will show you if you have any other cards that have the front side blank. If so, there will be a list with clickable links, and you can click on them one by one to investigate. Clicking on each link in that list will bring up the related note in the Browse window.
Thanks, a lot, again for your help. 
It is an issue with all the cards, for AllInOne notes, in all the decks, really. These notes have all fields correctly filled, there’s no problem at all. I mean, when I browse by notes and open anyone, all the fields are right, but when I browse by cards, all of them say “The front of this card is blank”.
In your previous message, the fields used in the template were called Title, Question, Answers, but in this screenshot you have fields named Pregunta, Tip de pregunta, Respuesta 1 and so on. So something is inconsistent here.
The code in my previous message appears truncated. It was audited by the webmaster previously to its publishing. If you agree, I could send you the code by email.
You can put two lines with
```
one before (above)
and one after (below)
the code from the Front template that you copy-paste here.
Then it should remain intact and display correctly here.
Maybe you can edit your message above to add the ``` lines.
Sorry, I cannot add ``` in my previous message. So:

It seems like the AllInone card template doesn’t exist and Anki is using the default one, but the note template is apparently right:
Again, apart from the scripts, the fields used in the template are Title, Question, and Answers, and I think the final field is controlled by the scripts.
But there are no such fields in the note, according to your screenshot. You have fields named Pregunta, Tipo de pregunta, Respuesta 1, and so on.
Your template doesn’t match the fields of this note type at all. It’s not clear how this could possibly work.
YEs, I agree, but I don’t know why before the updating the addon runs perfectly (Anki linked the note template with its correspondent card) and now the app doesn’t find the AllInone card template as before.
If it could help in something, this is the original card template. I just changed the names of the fields to Spanish and so on:
Renaming the fields broke the template.
Normally, when you rename the fields of a note type, the names are automatically changed in the template as well. I don’t know why this didn’t happen here.
So you should edit your Front template to change
{{Question}} to {{Pregunta}}
{{#Question}} to {{#Pregunta}}
{{/Question}} to {{/Pregunta}}
and similarly change Answers to Plantilla respuestas correctas
What happened to the Title field? Did you delete it instead of renaming it? You should either edit or delete that line in the template as well.
Finally, the template contains 'Q_' in three different places. However, you renamed Q_1 to Respuesta 1 and so on, so this part won’t work.
I don’t think a space is a legal character for ID names in HTML, so to allow the JavaScript code to work, you’d have to rename those fields to Respuesta_1 with an underscore instead of a space, and Respuesta_2 and so on, and then change 'Q_' everywhere in your template to 'Respuesta_'
But in older versions of Anki, it was working without editing the code. As I said, I change the field names, delete some of them and change the order but, everything was automatically changed and, anyway, the addon have been working fine.
Something changed between the former version and the new one. However, I tried to solve the issue returning to an older one, but I had no success.
So, I will change the template assuring the right linking between field names and I will check the addon performance.
Thanks, a lot, for your help.
