Upgrade my Nextcloud installation to 21.0.0. Works good so far but the log throws this error every 30 sek.

Got this error hundreds of times per minute. Disabling Notifications app stopped almost all of them.
(Nextcloud 21.0.0.9 via AUR package)

Thanks for the reply. I have tested this ... but to disable notifications is no option in a productive env.

Same problem for me too 👍

@deprecated since Symfony 4.2, use \Symfony\Component\Translation\IdentityTranslator instead

Same package, feel free to try it 😎

[Dual-0]

FYI I've updated to 21.0.1. Issue still exists.

[nickvergessen]

Yeah but its save to ignore.

PR is at #26375 coming with 22 so before the class will be removed.
