YES that is it !!! thats what i’m missing
On my web page it errors with:
Warning: file(http://www.wunderground.com/climate/extremes.asp): failed to open stream: HTTP request failed! HTTP/1.0 500 Internal Server Error in /home3/paul/public_html/usaextremes.php
When you said: “I have v4.03 of the script dated 13-Oct-2016” - which script are you referring to?
Thanks
