Internal Server Error

Hi everyone,

I am hosting WordPress on a Godaddy Linux Webserver. It was working fine until last week when I started getting an Internal Server Message on my live blog sites and in the WordPress Admin area.

I read some blogs about the error and it sounded like it could be a plugin. I did add the ShareThis plugin to the site last week so I deactivated the plugin and I am still getting the Internal Server Message! (As an aside my blogger had been unable to add images for a few days and when I deactivated the ShareThis the image feature worked fine again.)

What could be causing the error message? I recently:
1. added some static html code to the the sidebar area of my template
2. added static html code to the footer area of my template
3. turned the index.php page into a 3 column layout instead of the original 2 column layout that came with the template (using html and css)

Here is the url for the site with the altered template: http://neworleansmusiconline.com/wordpress/

The pages still load/refresh normally about 85% of the time, but the error message won’t go away.

Any help greatly appreciated.

Thanks!

Jill
