Hi,
Thanks.
I searched a little further and found something in the K2 forum:
http://
Social buttons languagegetk2.org/community/New-to-K2-Ask-here-first!/3065-Social-buttons-language
It's not the same, but i saw the same appid as i saw in the errormessage from Facebook.
And I had the same language problem as described in that topic.
After that I searched and found it in
components/com_k2/templates/default/item.php
There I changed the language setting to nl-NL (Dutch =))
I changed the 177.... id into my own appid and it worked.
Language was Dutch and I could login from the k2 pages.
Just wanted to let you know as maybe someone else will jump into the same issue.
Kind Regards,
Jan
