What were you playing around with?
If you are making changes to theme files (or any file for that matter) it is always best to make a copy of the file before changing it.
I did. Replaced it with the original and I still get this message.
<?php wp_list_cats(‘include=7,12,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,
29,30,31,32,33,34&hide_empty=0&show_count=1′); ?>

I am not seeing the error at the URL you mentioned.
Odd. I cleared my cache several times, etc. and the error always showed. Now it’s fine. Thanks anyway!
