That did it. It looks as if it was a coding error on the developer’s behalf. Line 91 of my code read:
<?endif; ?>
Which should have at least been coded as:
<? endif: ?>
(space before the endif)
I never thought to go through line by line in the code to see if the PHP notation had changed. It’s strange because every where else in the document, any PHP function is listed as:
<?php some sort of code ?>
Oh well. Thanks for the tip.
