Thanks Stephen, I edited my previous post. It was only that I wrote bbpress-it-IT instead than bbpress-it_IT 🙂
I now need to see how I can customise the files as some words in Italian are just too long and I find it better to abbreviate them. This plug in is great ^_^ And I am sure I will be writing for help again… 😀
I just followed the instructions to set bbpress in Italian but no luck, the basic page I created is still showing the headers in English (e.g.: Topis, Posts, Freshness, weeks, and so on).
I copied the latest .mo and .po from the development section and renamed them bbpress-it-IT.mo and bbpress-it-IT.po. Copied them as per instruction in the proper location. Was there anything else I had to do? I appreciate your attention, thanks.
EDIT: found the mistake, sorry, as you can see from what I wrote I used a dash instead than an underscore 😀 Sorry for the waste of time!
