Hi, I have a slight problem...
On my local server my app works as expected but when I deploy it, it presents each page twice, one under the other.
I don't know if it's related but on each round, the same participant is assigned to a different group (players_per_group = None).

If it matters, the pages are randomized using rounds, exactly as the example in the documentation says.

I am using otree<5

Thank you in advance,

Jasmine

Can you share your HTML template file for the page that is being duplicated?

And if you use an "include" statement in the template, also send the sub-template.

Is this problem solved? I have the same issue. When tested locally everything is fine. But once uploaded to Heroku there are pages which display twice on the same webpage one under the other

Can you post your full template?

I have seen issues like this happen when 2 templates have the same name that differ only by case, for example Instructions.html and instructions.html

It looks like this can also happen if the template uses {% extends %} at the beginning, but there is some space before the {% extends %}, for example note the leading space below:

{{ extends "global/Page.html" }}
{{ block title }}title...{{ endblock }}

That makes a lot of sense! I had to recreate all the pages by using the page template which didn't duplicate. It solved the problem but I couldn't figure out why. After seeing your answer, I simply deleted the space before {% extends %} and the duplication all gone!.

Appreciate the help!
