Hello
I changed the directory name of the tb_methys theme to reflect the name of the site (as I usually do with new sites).
As per usual, in order to do this I did the following steps:
1) change tb_methys.info name to sitename.info (where site name is... my sites name)
2) In the file template.php, I changed the following line:-
require_once drupal_get_path('theme', 'tb_methys') . '/inc/preprocess_functions.inc';
...changing tb_methys to reflect foldername.
After I reload the site, I get the following error:-
