When translating messages 22, 23 and 24 on the main feedback page, I get
the following mesage:

Error saving translation: This namespace is reserved for content page
translations. The page you are trying to edit does not seem to
correspond any page marked for translation.

I’ve kept my translations of these messages into French in a text file
so please don’t translate again.

Hi Sylvain
This error message comes from an occasional bug that is suspected to be related to the JobQueue.
TLDR: Wait a few minutes and try again - that usually solves it.
