Still some ctools related errors...... (further) research time!
Let's update the nodeaccess module & then run the Drupal's update process
cd modules/
rm -rf nodeaccess/
tar -zxvf nodeaccess-7.x-1.8.tar.gz
rm -rf nodeaccess-7.x-1.8.tar.gz
After clearing cache and reloading the home page: still the same ctools error on the home page :-/
Let's update the Mail System module... and reload the home page after clearing cache
Nope... still same errors!
