title: What does 'Template error at line 0' mean in django?
body: <p>I have got an error on a django site that i am working on which is a zero division error. I couldn't find the source of the error which I am thinking that is because of likely mathfilter but still not sure.</p>
  
  <p>What I am asking here is that django gives that error with saying it occurs at line 0 which I don't know what that exactly mean.</p>
  
  <p>This is the beginning of the template file:</p>
  
  <pre><code>1   {% extends "main.html" %}
  2   {% include "ru.html" %}
  3   {% load staticfiles %}
  4   {% load mathfilters %}
  5   {% load humanize %}
  </code></pre>
  
  <p>Only thing that occurs to me when I see this (error at line 0) is that to look at the main.html file. But I couldn't find anything that might cause this zero division error.</p>
