Hello,

First off, thank you so much for a valuable tool such as this!

However, I ran into a hickup today as I attempted to use a template part in the header.php file. I run into this error:

PHP Fatal error: Uncaught Error: Call to a member function get_template_part() on null in [MY PLUGIN FILE.PHP]:144\nStack trace:\n#0 [MY WP DIR]/wp-includes/class-wp-hook.php(305): [MYPREFIX]_banner_images(NULL)\n#1

[MY WP DIR]/index.php(17): require('/nas/content/li...')\n#8 

{main}\n thrown in [MY PLUGIN FILE.PHP] on line 144

In this specific example it mentions line 144 in my plugin only because I attempted to add an action to the header as a workaround. Here's what I tried in addition to editing header.php directly:

add_action('get_header', '[MY FUNCTION WITH TEMPLATE PART]');

Is there any way to get this working in the header?

There's not enough information here to reproduce or determine the issue. I'd need to see the custom template loader class that extends the Gamajo_Template_Loader, find out where those files are located, and see how you're are instantiating the custom template loader class and how/where you're calling get_template_part().
