The conflict is that when the plugin is activated the blogs do not display on the blogs page on the theme. They display on the home page of the site, but not the blog page. I deactivated all of the plugins on the site and reinstalled them, the blog page was working for all plugins until I reactivated the wordpress seo by yoast plugin.
I've currently deactivated the plugin and I'm using a different seo plugin on the site. I've used the wordpress seo by yoast plugin on all my other sites and want to use it on this site is possible.
