Thanks Ray but I'm moving a lot of domains and adding the leading slash sorted the problem and it has not surfaced on other sites so far.
One new issue that I see today is this error:
Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; WA_AltClassIterator has a deprecated constructor in E:\Websites\***redacted***
<?php
//WA AltClass Iterator
class WA_AltClassIterator {
var $DisplayIndex;
var $DisplayArray;
function WA_AltClassIterator($theDisplayArray = array(1)) {
$this->ClassCounter = 0;
$this->ClassArray = $theDisplayArray;
}
function getClass($incrementClass) {
if (sizeof($this->ClassArray) == 0) return "";
if ($incrementClass) {
if ($this->ClassCounter >= sizeof($this->ClassArray)) $this->ClassCounter = 0;
$this->ClassCounter++;
}
if ($this->ClassCounter > 0)
return $this->ClassArray[$this->ClassCounter-1];
else
return $this->ClassArray[0];
}
}
?>
<?php
//WA Alternating Class
$WARRT_AltClass1 = new WA_AltClassIterator(explode("|", "WADAResultsRowDark|"));
?>
This is a php 7.1 condition it seems.
