Here is the website
1) When I changed the featured image on the instructor page it does not show up on the main page. I have deleted and re added it several times. no go. I have no idea what to do here. Right now it is an ugly blank space
2) I have the posts limited on the main page but they still show up! Even stranger is that some of them show past revisions that are not present. I do not know what to do here.
