Thank you so much! Re saving my permalinks solved the issue.This might be more of a wordpress issue then a hosting issue, but a first step to try is logging into your wordpress admin area and go to permalinks section and check and re-save so they are rewritten to rule out there being an issue with those, which would case 404 (file not found errors).
I do see that your current .htaccess is empty, which makes me think this at least is a likely part of the problem.
