Changes impossible in Site page


I can’t modify content (title author description etc) anymore in Site parameter page :open_mouth:
When saving changes it just keep last content without saving the new.
When changes are done directly in txt file it is ok, but from admin panel nothing happens…
If someone have an idea…
Thank you for your help and suggestions

What version of Kirby is that? Do you happen to have more than one text file in that directory, maybe because you have switched from a single- to a multi-language setup?

Exactly, I was just writting a comment to say That.
I did a bad manipulation with language and it has created a 2 second text file.
Thank you.
