Django(1.9.6) list_display works on dev not prod
<p>I am running a local version of django on my computer as well as a django droplet at DigitalOcean, both Django 1.9.6. However, everything I have done this far has been the same across these two environment, but when I tried to customize the admin screen, it only worked on my local env. </p>

<p>The change I did was to add the following code to the app/admin.py.</p>

<pre><code>class PostAdmin(admin.ModelAdmin):
    list_display = ('post_title', 'pub_date', 'is_premium', 'source_title')
    list_filter = ['pub_date', 'source_title', 'is_premium']


admin.site.register(Post, PostAdmin)
</code></pre>

<p>But this customization is only shown on my local env... I have of course pulled and updated my code on DigitalOcean using Git. Just to make that clear. </p>
