For those using the Saratoga template, there's an easy way to keep the version checker happy AND switch to the older V4 advforecast2.php script.
First, download
https://saratoga-weather.org/advforecast2-V4.05.php?sce=view and save it as advforecast2-old.php on your site.
What you can do to use the old script AND keep the version checker happy is:
Then change Settings.php from
$SITE['fcstscript'] = 'advforecast2.php'; // USA-only NWS Forecast script
to
$SITE['fcstscript'] = 'advforecast2-old.php'; // USA-only NWS Forecast script
And your site will use the old script, and the version checker thinks all is well...
When the NWS api.weather.gov returns to full function again, you can put the original setting back and restart using the V5 JSON script again.
