Here's the message I'm now getting using the "Silence" theme and working with Content Slider plug in:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@brimelow.net and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

I just set up this site so It's not a problem to reinstall it and start over if that's necessary. Thanks for your input.
