In the CComment Core version, the support emoticons options under layout is ON (and you can't change this in the core version).
But if you see the config SQL value in the table `dqobg_comment_setting` for 'com_content' entry, there's no param 'support_emoticons'
but if you go in "Comment configuration for com_content", do nothing just "save & close", the param disappear...
PS : I have bought the PRO version => no problem with it
Thanks for your attention
