I just swapped the errorpage I did with the one downloaded (html/php version) that you provided - it also doesn't report the errors
The domain that this is being used for is an add-on domain not my "root" domain.
Should I express the URLs in the form of
http://www.windgigs.com/cedarairvents/errorpage.php
rather than:
http://www.cedarairvents.com/errorpage.php
Shouldn't make a difference?
