Pages Will Not Load

When I enable the YOAST plugin none of my pages will load on the site, they all error out. When I disable the plugin they all begin loading again no issue. I even tried disabling all other plugins, pages still will not load with YOAST being the only activated plugin.

Any idea what might cause this?

I am updated to the newest version. Everything is updated and I am using the highest level of shared hosting from siteground.com so hosting should not be an issue. I just switched in fact from Bluehost to Siteground and same issue on both hosts. I have another site on Siteground on the same plan using YOAST without an issue.
