 * 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:
 *     ```wp-block-code
       [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:
 *     ```wp-block-code
       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:
 *     ```wp-block-code
       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.

 * Update: I pushed that change to my live site and everything still seems to work.
   It definitely silenced the warning.
