Reply To: Language files are ignored
You are correct, the string Last comment, Topics/Replies are NOT bbPress strings, these strings will be in either the theme you are using with custom bbPress templates or a plugin you are using.
As a side note, WordPress 3.9 and bbPress 2.5 and above versions no longer need define(βWPLANGβ, βtr_TRβ); in wp-config.php, and coming in WordPress 4.1 you can select your language from in WordPress settings π
The biggest advantage of the above is translations will be included when you update WordPress or bbPress, the only condition to receive the language packs automatically is that the language pack is 100% translated, if that is the case then translations are automatically delivered. π
It would be amazing if you could help get the Turkish locale 100% for bbPress π If you use BuddyPress that would also be awesome, WordPress is already 100% π
