Hello Vlad,
Sorry for late reply to this,
It seems like you provided that login credentials is still not working.
By the way, can you download my attachment file and replace in
JoomlaFolder\administrator\components\com_easysocial\views\users\view.html.php
It should fix this issues.
This issues only occur in Joomla 2.5. Please consider update to Joomla 3.x in your future.
