Hi, if you have newer versions of php installed on your server you will notice that plugin doesn\u00b4t work. That because “array_column” function was deprecated. You must code your own function for that. The next code is a solution for that problem. Paste it on the top of mail2users.php file (behind first coments): <\/p>\n
if (! function_exists(‘array_column’)) {
\n function array_column(array $input, $columnKey, $indexKey = null) {
\n $array = array();
\n foreach ($input as $value) {
\n if ( !array_key_exists($columnKey, $value)) {
\n trigger_error(“Key \\”$columnKey\\” does not exist in array”);
\n return false;
\n }
\n if (is_null($indexKey)) {
\n $array[] = $value[$columnKey];
\n }
\n else {
\n if ( !array_key_exists($indexKey, $value)) {
\n trigger_error(“Key \\”$indexKey\\” does not exist in array”);
\n return false;
\n }
\n if ( ! is_scalar($value[$indexKey])) {
\n trigger_error(“Key \\”$indexKey\\” does not contain scalar value”);
\n return false;
\n }
\n $array[$value[$indexKey]] = $value[$columnKey];
\n }
\n }
\n return $array;
\n }
