I have added a new Web Site Language in 'Manage Web Site Language' (via CMS --> Admin Mode --> Config tab --> Manage Web Site Languages).
I expect to see this Language in the Language dropdown in the 'Show page tree:' in the bottom left corner (in CMS --> Edit Mode), but the language is not there.
How can I make sure the language appears here?
Thanks Linus, for your response.
After triple-checking every language configuration, I found that under 'Manage Web Site Language' (via CMS --> Admin Mode --> Config tab --> Manage Web Site Languages) I did not Add Users/Groups to the languages I just added (argh). After adding 'Everyone', the language were visible in the language dropdown, and I could add the language to the particluar web site.
Thanks for your help!
