Hi doug,
This is not the theme issue. It is server issue. So you may contact to the server provider to increase the upload memory size.

Just try this plugin before contacting to server provider

https://wordpress.org/plugins/increase-upload-max-filesize/
https://wordpress.org/plugins/pbp-increase-upload-limit/

or you may add this code inside wp-config.php
define('WP_MEMORY_LIMIT', '64M');

or
