I tried to install freichat after a very long time. I was trying to install freichat on wordpress 4.8 with buddypress installed but the chat was not showing up on front-end even when the provided code at the end of freichat installation was placed in header.php before </head> tag after <?php wp_head(); ?>. I tried to install it twice but the result was same however admin panel of freichat was working properly. Log file was showing entries of current loggedin user being inserted in db table with "I am available" status. Admin panel was showing list of registered users on wordpress.
One more thing, if freichat starts working then how I can make the chat friend only. I have done this before via custom driver but that was a custom php website.
I tried installing freichat on a wordpress v4.4.10 with nearly the same setup on localserver. The installation wizard entered wrong db prefix "usermeta" in hardcode.php but after fixing it the chat started working. So to confirm again I tried to install freichat on live server but it again failed to show up. Could this problem be related to my VPS? PDO-MYSQL is already installed on my VPS. I have enabled server wide gzip compression & running modpagespeed which is handling server side cache. While URL FOpen, URL Include and following functions are disabled:
