Thanks for the response. Meant to log on and say I figured it out.
I failed to see up this thread that mystile is a THEME. Duh.
I don't use that theme, so don't have the menu options you all are telling me to go to.
But I did find that one of my plug-ins was causing that entire first part of my profile to disappear. It must just not have been compatible with the Aspen theme I use. I deactivated all of my plug-ins and the profile function came instantly back. Then I updated WordPress, and Aspen. Then I started with the most basic plug-ins I knew I needed, loaded them. Then I loaded the rest one at a time keeping a window open to the profile admin page. Presto. When I activated that one in question, the top part of the profile admin page disappeared. I deactivated that plug-in, and it came right back.
I can't remember the plug-in name, but it was to remove the web address field from post comments.
Thanks for the reply.
