First off, I want to say that I really like your extension, it has a very user friendly interface for inserting products into WordPress.
However, the first time I tried to insert a product, I got the following error message:
Fatal error: Class 'Magento_Template_Helper' not found in /home/comple59/safetyawardsource.com/wp-content/plugins/magento/classes/Magento.php on line 371
I was able to compensate for the error by adding a line just above the class call:
This may be an issue you will want to address in future updates.
I just thought I'd post this in case anyone else has a similar issue.
