How do i configure freichat only to show only last 5 messages received and not all of message history?

You can add a LIMIT in the sql query defined in $getdata_query around line 786 in server/freichat.php

yes, but it opens last 5 chat conversations, instead of just seeing last five messages of each conversation i open

Yes but i get 5 last chat conversations, not 5 last messages...

nevermind i found it on line 840, thank you
