# Theme problem, getting Fatal Error message

 * When I am in the wp-admin panel looking at the themes I have available, they 
   look fine. When I look at the previews, they look nothing like what the themes
   are supposed to look like. There are no graphics and everything is out of place.
 * On the right side of the preview, I have the following message displayed”
 * Fatal error: Call to undefined function art_sidebar() in /home/chipstac/public_html/
   wp-content/themes/CosmicLight/images/sidebar1.php on line 2
 * If anyone has some advice on what to look for to correct this so I can use this
   theme, it would be greatly appreciated.

 * There’s a function in the CosmicLight’s sidebar1.php file that has not been defined
   either in that file or in the theme’s functions.php file. Try either uploading
   a fresh copy of the theme or contacting the theme’s author.
