無效的塊標記：'static'

服務器返回 TemplateSyntaxError at/ Invalid block tag: 'static' on this line：<img src="{% static 'icon/logo.png' %}">。無效的塊標記：'static'

的whold HTML文件是這樣的（它是一個HTML文件{％包含％}由另一人編）：

{% load staticfiles %} 
<div class="header"> 
    <nav> 
     <ul class="nav nav-pills pull-right"> 
     <li role="presentation"><a href="{% url 'offer rank' %}">潮品榜</a></li> 
     <li role="presentation"><a href="{% url 'user rank' %}">達人榜</a></li> 
     <li role="presentation"><a href="#" data-toggle="modal" data-target="#start">登陸</a></li> 
     <li role="presentation"><a href="#" data-toggle="modal" data-target="#start">註冊</a></li> 
     {% if debug_users %} 
     <li class="dropdown"> 
      <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">切換用戶<span class="caret"></span></a> 
      <ul class="dropdown-menu" role="menu"> 
      {% for debug_user in debug_users %} 
      <li><a href="{% url 'debug login' debug_user.id %}">{% if debug_user.kbjuser.user_type == '1' %}達人{% else %}商家{% endif %}: {{ debug_user.username }}</a></li> 
      {% endfor %} 
      </ul> 
     </li> 
     {% endif %} 
     </ul> 
    </nav> 
    <h3><img src="{% static 'icon/logo.png' %}"> 
     <a href="{% url 'home' %}" class="text-muted">口碑街</a> 
    </h3> 
</div>

而且settings.py是這樣的：

# Static files (CSS, JavaScript, Images) 
# https://docs.djangoproject.com/en/1.7/howto/static-files/ 

STATIC_URL = '/static/' 
STATIC_ROOT = os.path.join(BASE_DIR, "static/") 

MEDIA_URL = '/media/' 
MEDIA_ROOT = os.path.join(BASE_DIR, "media/") 


from hw.settings import * 
from useraccess.settings import * 

STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder', 
    'django.contrib.staticfiles.finders.AppDirectoriesFinder', 
    # other finders.. 
    'compressor.finders.CompressorFinder', 
) 

COMPRESS_ENABLED = True

我無法弄清楚這裏發生了什麼。

這裏有一些行settings.py：
