I update photos for a site which uses PHP, something I don't know much about, and usually never have to mess with. Recently, the "Site Last Updated" function has ceased to work. It displays a date and never changes when the photos are updated. Does anybody see anything wrong with this code, or can you at least give me a clue where to look to correct this? Thanks in advance.
<?php
$filemod = filemtime("/usr/local/var/gchs/animals.ISD");
$filemodtime = date("F j Y h:i:s A", $filemod);
?>
<p align="center">
<font face="arial,helvetica,sans-serif" size="1">
Site Last Updated: <?php echo $filemodtime;?>.
</font>
</p>
