So, it appears my problem persists.
Along with the AQI not showing up, I also was experiencing some slow access times.
Events, 3 or so weeks ago accessing pennlake.us was very slow at times.
About 3 days ago I enabled url_fopen on the server and the AQI started to display.
Still loading slow my sever provider uploaded a newer version of PHP 8.2.16 and my site loads quickly now.
Except the AQI was not displaying again –
Url_fopen is on or enabled now but the AQI is again not displaying.
Back to the drawing board, lol.
