PHP Warning: “Undefined array key “pci_osm””

Hi all, thanks as always for this incredible plugin and all the support you put into it.

I discovered another one of those classic little bugs where an edge-case results in PHP warnings in the logs:

[18-Aug-2025 16:50:23] PHP warning: "Undefined array key "pci_osm"" file: [...]/powerpress/powerpress.php:1498 url: globalvoices.org/-/special/global-voices-podcast/feed/ 

Seems easy enough to fix, as the code just doesn’t validate that the array item isn’t empty before checking if it’s an array:

if( !is_array($Feed['pci_geo']) && !empty($Feed['pci_geo']) ) {
     echo " geo=\"" . htmlspecialchars($Feed['pci_geo']) . "\"";
}
if( !is_array($Feed['pci_osm']) && !empty($Feed['pci_osm']) ) {
     echo " osm=\"" . htmlspecialchars($Feed['pci_osm']) . "\"";
}

Seems to me all we need to do is flip the order so it checks !empty() first, then check if it’s an array:

if( !empty($Feed['pci_geo']) && !is_array($Feed['pci_geo']) ) {
     echo " geo=\"" . htmlspecialchars($Feed['pci_geo']) . "\"";
}
if( !empty($Feed['pci_osm']) && !is_array($Feed['pci_osm']) ) {
     echo " osm=\"" . htmlspecialchars($Feed['pci_osm']) . "\"";
}

I wasn’t able to replicate this issue using a local test site, but I’m going to update my live site and confirm this solves the problem for me and reply back.
