I am having some trouble with the Text Widget in the Sidebar.

Why is the body text next to the widget title? It should start under it, not next to it.

I have attached a picture of my situation. Any suggestions and/or help is appreciated. Thanks in advance.

without seeing the site it's hard to say what is happening.

I decided to see if any of my plugins were causing the problem.

It turns out that the plugin "WP Accordion Slider" was causing the problem.

Do you know of any issues with this plugin and the Atahualpa theme that would cause the problem shown in my picture?

Worst case I will just have to live without the plugin...

No I know of no issues, but that's not saying there isn't. To see if it is theme or plugin relates, temporally swap to the twenty ten theme. If the issue shows, it is a plugin conflict, if not, it could be a Atahualpa issue.
