Look into class.gettext.php - Line 406:

$msgstr ??= null;

I don't know this syntax in PHP but if i comment out the line everything works without error.

What's the problem here?


Edit: complete function:

private function parsePOEntry($chunk)
    {
        $chunks = explode("\n", $chunk);
        foreach ($chunks as $chunk) {
            if (starts_with('#', $chunk) or is_null($chunk)) {
                continue;
            }
            if (is_null($this->translation_plural) and starts_with('"Plural-Forms:', $chunk)) {
                $this->parsePluralData($chunk);
            }
            if (preg_match('/^msgid "(.*)"/', $chunk, $matches)) {
                $msgid = $matches[1];
            } elseif (preg_match('/^msgstr "(.*)"/', $chunk, $matches)) {
                $msgstr = $matches[1];
            } elseif (preg_match('/^#~ msgid "(.*)"/', $chunk, $matches)) {
                $msgid = $matches[1];
            } elseif (preg_match('/^#~ msgstr "(.*)"/', $chunk, $matches)) {
                $msgstr = $matches[1];
            } elseif (preg_match('/^msgstr\[([0-9])+\] "(.*)"/', $chunk, $matches)) {
                if ($matches[2] == '') {
                    continue;
                }
                if (!is_array($msgstr ?? null)) {
                    $msgstr = [];
                }
                $msgstr[$matches[1]] = $matches[2];
            }
        }
        //$msgstr ??= null;
        if ($msgstr == '') {

                'msgstr'=> is_null($msgstr) ? null : (array)$msgstr
            ];
        }
    }

Chevereto V3.20 requires PHP 7.4, you are having issues because you aren't using PHP 7.4
