Warning: Cannot modify header info
« on: March 28, 2018, 09:10:00 PM »
http://cvweather.org/?sce=view

Yields errors on my Burnsville modified Saratoga template.

Discovered this while trying to determine why my mobile site shows expired alerts http://cvweather.org/mobile-dashboard.php

Don't know if these are related issues.

Any suggestions appreciated.

Thanks

Im sure Ken will be able to help more with the details but this line is showing your testtags file is 2 levels up compared to your other files.

The ?sce=view is a small snippet of code added to many of my scripts to allow the PHP source code to be remotely viewed (useful for debugging purposes and remote support).

When you try it on the index.php page with just /?sce=view, then the first script loaded that has that capability will display it's own source, and exit.  In template pages, the first script with that capability loaded is likely the weather tags file (testtags.php for Weather-Display). The wx...php (and by extension the index.php page) do not have that ?sce=view capability installed, so it's no wonder you get unexpected results .. it's not a bug.. it's just the way it works.
