1) Po file is declared in utf8
2) Greek doesn’t face any issue in any character, as I all ready translate almost 800 wording wihout any issue (every character appears ok).

As a matter of fact I changed the “%1$s and %2$s are now friends” with “%1$s test %2$s” and still I get “%1$s and %2$s are now friends”.

So it’s something that hasn’t to do with language.

check bp-friends/bp-friends-functions.php:100 and 109 for the original BP wording.
Check also the po file who must be declared in utf8.
See also if the greek wording use some special characters, like apostrophe who must be in html and not in natural typing

Example:
The letter zeta is usually ζ but must be written & zeta ; or & #950 ; (without space) if used in a php function or a js part.

I (at least) double checked the translations. I did reload the page one thousand times

Every other change I make it appears immediately. It is weird…

double check what you translate is correctly writen.
Ie, %1$s joined the group %2$s
The mandatory part must be %1$s (the username) and %2$s (group name) Only joined the group is in greek.
Same thing for %1$s and %2$s are now friends. “and” and “are now friends” can be translated.

If you already did this correctly, it could be that you’re victim of gettext latency. When a server is busy, you have to reload several times the page to refresh your browser, or to wait a little while.

Also, since 1.7, template & localisation are hanging in some case because of a weird loading priority affecting bbp and BP. It’s not the reason why you can’t get a translation, but it may be an explanation about a buggy environment.

I use bp-default and I use Greek.

Thank you

What theme and language do you use ?

I struggle to find out a solution on translating specific wordings of buddypress.

I have translate the 80% of the language file and everything looks perfect except some specific lines that seem just untranslated…

For example ” UserX joined the GroupZ”. I translated this line but still is untranslated. (I also joined a group, after translated this line).

Then I translate the line “UserX and UserZ are now friends” but still remains untranslated.

The weird thing is that if I translate or change anything else, it will be translated.

Both the lines I mentioned as examples are displayed in Activity steam, so it might has to do with this. I really don’t know.

“Include language slug for BuddyPress URL’s

Not sure if it’s qTranslate or BuddyPress related, but I found a nice way to modify all BuddyPress URL’s to include qTranslate language slug.
To do that, I had to do the following changes in qtranslate_hooks.php:

    //comment out next line, otherwise 404 page is displayed
    //add_filter('clean_url',                  'qtrans_convertURL');
    //include language slug in all BuddyPress URL's
    add_filter('bp_core_get_root_domain', 'qtrans_convertURL');

Hope you can include this into next verison of qTranslate plugin.”

Checked. Working.
Yes, logic buddypress is so special that the hook can not do without. (

loubas – A long time ago wrote about the problem.
Does not anyone know how to fix this deficiency?

In some cases, it is more logical to use qTranslate (no WPML).
Did not the developers are working in this direction?
I would be very grateful to those who tell me a way around this problem.
