A guest I invited to view my blog sees a different layout than what I have created. For instance, I created a menu of 5 pages from left to right on the main page, but what she sees on her computer is one menu button that when clicked displays the page names vertically. After clicking the a link she can view the page, but then the one menu button appears. I also have a hierarchy on one page-parent/child/child, but that hierarchy isn't displayed on hers. The font also changes. I'm using Chrome and she's using IE. What's going on?
The blog I need help with is tri4arthritis.wordpress.com.
