How do I change the post date format in the Articles add-on?

Question

MODX

PHP Version 5.6.13-pl0-gentoo
MODX Revolution 2.7.0-pl
Using the article publishing module Articles 1.7.11-pl
1. Create a resource of type "Article" called "News". I add the first news "test" without publication.

2. Trying to publish the "test" news, updating the content page of the "News" resource.

The result - the news disappears from the list of articles.
The reason for this error and how it is reproduced:
1. Go to mySQL in the modx_site_content table, see that the news is in place:

2. change the publishedon attribute of the "test" entry to 0. Update the news resource view page, and the news is again in the list, and it is also available at http:
3. Again I publish the news "test".
4. I look at the core/cache/logs/error.log log
When viewing a news resource, an error is added there:

[2019-02-12 12:48:25] (ERROR @ /....../htdocs/core/model/modx/modprocessor.class.php : 264) Processor failed creating output array due to JSON error 5

5. Go to the modprocessor.class.php file to get the details:
a) Get the content that we tried to jason from $array and the $trace function call stack:

public function outputArray(array $array,$count = false) {
        if ($count === false) { $count = count($array); }
        $output = json_encode(array(
            'success' => true,
            'total' => $count,
            'results' => $array
        ));
        if ($output === false) {
            ob_start(); 
            debug_print_backtrace(); 
            $trace = ob_get_contents(); 
            ob_end_clean(); 
            $this->modx->log(modX::LOG_LEVEL_ERROR, 'Processor failed creating output array due to JSON error '.json_last_error().print_r($array, true).print_r($trace, true));
            return json_encode(array('success' => false));
        }
        return $output;
    }

6. After editing, the error log gives the following details:

When displaying a list of news in the admin panel, the publication date on the server side is formed with Cyrillic characters in the wrong encoding, the publication object cannot be serialized into JSON and passed to the admin panel frontend.

Answer 1

I recommend looking in "Advanced settings" -> "General" -> "Articles URL Format", the parameter at the very end.
There should still be parameters, I won’t say more precisely now.
UPD. You need this:

Answer 2

The solution turned out to be in the config file: \ htdocs
\core\cache\system_settings\
config.cache.php
