Using original chats instead of QuakeNet to reproduce this.
I'm having an issue with Twitch chat complaining that it's too small, getting the error message, which I fixed myself by changing
$heightIRC from 250 to 301 on lines 127 and 140 in
page-frontend/page-livetreams.php. Unfortunately, I have to do this after every update right now.
Also, having "default title h3" set to "No" in the settings doesn't hide it, but displays "ARRAY". This is an error, and is caused by a $temp variable being used but not initialized in line 188. Inserting a
$temp = ''; on line 178 fixes this.
