Theme Warning messages after moving WP to root

Hello,

Not sure which is the correct forum to post this in.....

We installed WordPress into the root, moved it to a WordPress directory to work on it and then moved it back to the root. When we moved it back to the root we got these messages. Can you help resolve? We're not sure what the problem is. The site is here.

Warning: sort() expects parameter 1 to be array, string given in /home/ashevil3/public_html/wp-content/themes/atahualpa/functions/bfa_rotating_header_images.php on line 42

Thanks so much!
