Hello,

Everytime I sync albums I have this message repeated X times (the more photos it has to sync, the more it appears)
" Warning: Invalid argument supplied for foreach() in /volume2/web/piwigo/plugins/exiftool_gps/main.inc.php on line 23"

And it ends with "Warning: Cannot modify header information - headers already sent by (output started at /volume2/web/piwigo/plugins/exiftool_gps/main.inc.php:23) in /volume2/web/piwigo/include/page_header.php on line 94"

Piwigo is installed on a Synology device.

What can be the problem ? Thank you in advance for your replies ?
