Header class Implode Error (customizr/inc/parts/class-content-headings.php)

Hi,

I’m using the lates WP and Customizr theme with the latest DWQA plugin, which introduces a Custom Post Type to the system for a Quota style Questions and Answer system.

The problem is on the Archive, Category and Tag pages linked to that plugin – they all show up with no content below the header.

This error appears in the page HTML for the header class inside #content:

<header class="
<b>Warning</b>: implode(): Invalid arguments passed in <b>/wisdomcloud.org/wp-content/themes/customizr/inc/parts/class-content-headings.php</b> on line <b>115</b>
">


It looks like somethings going wrong when it comes to Customizr working out what template parts to use?

Is there a known fix?

Here’s a link to an offending page:
