Django OpenStack Horizon - Admin templates are not rendering properly
<p>Upon creating my own panel in OpenStack Horizon I am unable to properly view the admin panels (Overview panel: Pie Charts not appearing, Instances: Unable to generate Instance but can view possible instances to choose from). This occurs when my new panel is 'enabled' within the enabled folder. The panel that Ive added is not Horizon-centric, and the 'magic' of Horizon is not taken advantage of (I find its syntax odd). Any idea as to why the admin panels are no longer rendered properly? It seems to be a template issue but I have no idea how to fix it. </p>

<p>Within settings.py I am pointing to the newly created templates, this however is not needed if Horizons syntax is utilized (So I believe). Ive also got static files (css) rendering the new panel, not sure that this matters. Any help would be greatly appreciated!</p>
