Re: Tiki 9.x and phpfreechat
hi: ni idea. Try it in your localhost first.
Alternatives: the minichat module bundled in tiki: it only lacks the date in the time stamp.

PS1: you can restore from backup. And in short, you can restore to a different folder, and adapt whatever settings you need in your control panel from your hosting, if needed.
PS2: run again 'sh setup.sh' if you have ssh access, and you will have permissions set for you. Or 777 through ftp if that's easier for you. Or check the setup.sh script locally and see which folder should have which permissions, etc., if you want to tweak that more by ftp (if y ou don't hace ssh access).
And welcome to the Tiki Community!
