Dear All,

I have php error at logging, How I can fix it.

Nextcloud version (eg, 20.0.5): 20.0.5
Operating system and version (eg, Ubuntu 20.04): Ubuntu 20.04.1 LTS
Apache or nginx version (eg, Apache 2.4.25): Apache/2.4.41 (Ubuntu)

Is this the first time you’ve seen this error? (Y):

Steps to replicate it:

This appears to be related to something in the translation strings (despite that I use Nextcloud in default English)

        public function __toString() {
                $translations = $this->l10n->getTranslations();

                $text = $this->text;
                if (array_key_exists($this->text, $translations)) {
                        if (is_array($translations[$this->text])) {
                                $fn = $this->l10n->getPluralFormFunction();
                                $id = $fn($this->count);
                                $text = $translations[$this->text][$id];
                        } else {
                                $text = $translations[$this->text];
                        }
                }

                // Replace %n first (won't interfere with vsprintf)
79             $text = str_replace('%n', (string)$this->count, $text);
                return vsprintf($text, $this->parameters);
        }

I think it’s safe to ignore it, it went over after 2021-07-19 for me, I probably did a Nextcloud update then which fixed the error.
