Thanks for the response Michael. As an update to this, it wasn’t an issue with the database or the WordPress install because switching to a different theme had the blog posts showing up correctly. We couldn’t figure out what could possibly be causing the issue as, again, nothing with regard to how the post content was being called on the blog page had been altered, only this plugin had been installed and used. We ended up having to replace the wp-content folder from a back-up we had on file – which fixed the issue.
