Can't set second content languate to en-GB Topic is solved

[ldor]

Hi,
I am trying to setup an bilingual site. The default front-end language will be Turkish, the second language will be English.
When installing Joomla! I chose English as default. I then added Turkish. Now I see both English (en-GB) and Türkçe (tr-TR) in the list of Installed Languages. But there is no English (en-GB) in the list of Content Languages. I tried to add English (en-GB) manually but the system does not allow me to set URL Language Code to 'en'. I says "A content language already exists with this Image". Then I tried to add English (en-US). But again I cannot change the URL Language Code to 'en', again I get the same error message. So with en-US my site's URL looks like www.mysite.org/en-us but I need it to have /en at the end of the URL, not /en-us. What am I missing here?

I've found the reason. I checked jos_languages table in the database. The field "published" for English had a value of -2. I changed it to 1 and then English en-GB appeared in the list of content languages.

I am not sure why this happened but probably it is related with migration (I am migrating an old Joomla 1.5 site, not creating a site from scratch).

Anyway, the problem is solved now. Thank you everyone who read this post for your attention.
