Guys, do the same thing as Steve did.
1. Make sure that here: ow_plugins/friends/bol/service.php following text key is used: friends+newsfeed_action_string
2.In admin panel>>settings>>language>>find following text key friends+newsfeed_action_string
Make sure that is has following value: <a href="{$user_url}">{$name}</a> are now friends
INCORRECT VALUE: <a href="{$user_url}">{$name}</a> and <a href="{$requester_url}">{$requester_name}</a> are now friends
It was exactly it is!.. This solves most of it but it still exist same problem.
