Hi,

Do you have edited any language files, or languages strings ?

This display is due to an error in a language file. So the translations are not loaded.
Thanks to put the translations with their original content.

Hi

No, I havent edited the language files. I change the backend language to Danish, and I just reset it to English, but with the same result.

What should I do to fix it?

Hi,

Thanks to enable the Joomla debug language option in the joomla global configuration.
That will display the errors in the language files, then you will be able to edit the content of the indicated lines.
