I see a couple places where there are spaces outside of the php tags, spaces outside of the PH tags will cause the redirects to break.
the first place is a space before the first php tag at line 1. the code at line one starts with a blank space:
" <?php"
that blank space should not be there:
"<?php"
the second instance is a blank line at line 12.
lines 9 - 13 are:
<?php
$eCart1->GetContent();
?>
<?php require_once('Connections/help4health.php'); ?>
the blank line at line 12 should be removed:
<?php
$eCart1->GetContent();
?>
<?php require_once('Connections/help4health.php'); ?>
