Hey there @islands501,
Thanks for being a part of the community!
Since you've deleted/renamed your .htaccess and turning off the plugins didn't work, I would think it's either (a) your theme or (b) some sort of core file corruption of the WordPress installation itself. Have you turned on debugging to see if it gives you any sort of detailed error statement? If not, you can do so by following these instructions.
Also, what is the domain? I'll take a look and see if I notice anything.
