Hello all,

we encountered a bug with the original flow setting when loading the posts of a certain category (header menu click on the category). This occurred after we entered quite a number of posts. The demo doesn't show this but has also only few posts.

Symptom is that a javascript error would show "html object not found" and no posts would be loaded.

We found as a cause that there is conversion of html to json in blog-functions.php function flow_elated_get_archive_page_html. Even with the DB connection set to use UTF-8 there seems to be occasional invalid characters possible when creating posts. Hence the call "json_encode($return_obj);" is failing silently and nothing is returned back.

We added a wrapper and now it works  - just FYI for everyone who runs into the same:

(a) old code

echo json_encode($return_obj); exit;

(b) new code

$encoded = json_encode($return_obj);
if (json_last_error() == JSON_ERROR_UTF8) {
       $clean = utf8_converter($return_obj);
       $encoded = json_encode($clean);  
}
echo json_encode($encoded); exit;

function utf8_converter($array)
{
    array_walk_recursive($array, function(&$item, $key){
        if(!mb_detect_encoding($item, 'utf-8', true)){
                $item = utf8_encode($item);
        }
    });
    return $array;
}
