Both copies of the queryobj.php files are version 2.22.
I copied the queryobj.php and the latebreaking.php files from my iMac to my Macbook and now the latebreaking.php file works perfectly on my Macbook. When I compare the error lines (493) on both the 'good' and 'bad' files, I can see no difference. Please see the attached screen capture and both the good & bad queryobj.php files. Any ideas?
