[Solved]-Could not parse the remainder for boolean operators in django template

https://docs.djangoproject.com/es/1.10/ref/templates/builtins/#id4, i think the problem is that you forgot the space betwen the operator and the variable.
foorloop.counter <= 12

The parser used by Django templates fails to parse the values if there is a lack of whitespace around the operators. There was a ticket #27022 opened on Django’s issue tracker but it has been marked as "wontfix" in an effort to enforce a consistent style in templates.

Hence you need to update your code and add spaces around the operators:

{% if forloop.counter <= 12 or forloop.counter >= 25 %}
