# Array_keys() [function.array-keys]:

 * I’m a complete novice and have no idea what happened–tried to change some file
   names and received this error message (ErrorDocument 404 /index.php?error=404),
   so changed the file names back, but now on the wordpress dash, I have the following
   message:
 * array_keys() [function.array-keys]: The first argument should be an array in /
   home2/domain/public_html/wp-includes/theme.php on line 513
 * Is there something straightforward that I can do to fix this or should I installed
   WP through my shared host using Simple Scripts–should I uninstall it and try 
   reinstalling it? Thanks very much!

 * You renamed some of the WordPress core files? Try re-uploading all files & folders–**
   except** the wp-content folder – from a **fresh** download of WordPress.
