WordPress loop not working on page template

Hello,

I have an issue that has me dumbfounded … I have a site for a client where I am using a custom theme I built. I have created a page template for the blog and included the WP loop. The loop doesn’t seem to be working in association with any pages.

Here’s the rub … I have the exact same code on the template php file as I do for the index php file with the exception of the php template tag needed to tell WP it’s a page template.

Here’s the page – https://www.sourcingchange.com/discus/
Here’s a properly functioning category page using the same code without the template tag – https://www.sourcingchange.com/category/main/

Anyone have a theory, or solution?

Thanks … Scott
