Hello PauloV,
Need your advice,
I'm already installing this plugin, when i click live chat menu on admin blesta site.
it go to this link -> http://www.mysite.com/plugins/live_chat/vendors/blc/index.php/site_admin/
and its showing a blank page.
Fyi, in my server blesta installed on /var/www/html/blesta and i do virtualhost apache to access blesta site direct to mysite.com not on subfolder domain (www.mysite.com/blesta).
thanks,
