I get these errors after clicking on a Flickr album:

Could it be because I couldn't find the Callback URL mentioned in https://piwigo.com/blog/2013/05/21/import-from-flickr-to-piwigo2/ ?

This is apparently as the module doesn't seem to support PHP > 7. Obviously, you guys use PHP 7.2 or above. There are less errors and warnings in PHP 7.1 (supported until Dez 2019). However, it still doesn't work.

I got it to work by making 3 changes in piwigo/plugins/flickr2piwigo/admin/import.php:

line 189:
change
$all_photos = $all_photos['photoset']['photo'];
to
$all_photos = $all_photos['photo'];

line 199:
change
$existing_photos = array_map(create_function('$p', 'return preg_replace("#^'.$flickr_prefix.'([0-9]+)\.([a-z]{3,4})$#i", "$1", $p);'), $existing_photos);
to
$existing_photos = array_map(function($p) {return preg_replace("#^'.$flickr_prefix.'([0-9]+)\.([a-z]{3,4})$#i", "$1", $p);}, $existing_photos);

line 222:
change
$all_elements = array_map(create_function('$p', 'return \'"\'.$p["id"].\'"\';'), $all_photos);
to
$all_elements = array_map(function($p) {return $p["id"];}, $all_photos);

Thanks for the above fixes. Now things are working except for this intermittent error. Any ideas?

I guess I spoke too soon because now I am receiving another error involving photo data and arrays:

Warning: in_array() expects parameter 2 to be array, null given in /home/fncllorg/public_html/photos/plugins/flickr2piwigo/vendor/samwilson/phpflickr/src/PhotosApi.php on line 129
