Just as a heads up...

It seems as if the "About Me" plugin somehow conflicts with the backend of Atahualpa. When its installed and activated I found that it makes (at least) the HTML/CSS Inserts entries disappear. It doesn't *actually* make all of your inserts go away, just not show. When you deactivate "About Me" the inserts will reappear.

I'd stay away from this plugin

the "About Me" plugin hasn't been updated since 2010-1-8 -
Many reported problems and no responses
I would guess it has been abandoned...

Yep,
Shows to go ya that just because it's in the WordPress.org repository, there's not a guarantee that evey plugin will work as advertised.

Caveat emptor!

I decided to look at the About Me plugin and the one I found was updated in Feb 2012. I installed it and what it did for me is just collapse the CSS Inserts box. I was able to expand by dragging the corner.

Yup, there is an 'About Me' plugin (updated 12-2-20)
and an 'About Me Widget' plugin (updated 10-1-8)
(there also an 'About Me 3000 Widget' and 'About Me Sidebar' plugins)

So which one were you using?
