I think you may have gotten confused....the ini errors were on the integramod site, not mine...was just reporting the issue in case you didn't know about it.
My chatspot problem, however, remains unchanged...I haven't changed anything else, but I've been poring through everything I can think of.
I'm afraid I'm no php expert, so for me to uninstall chatspot and install the other would be problematic for me, without detailed instructions. Also, does it integrate with the phpbb sessions so that only logged in users may use the chat, and with their phpbb username showing as their chat name?
On a side note, it's on a server at home, not a paid host. I can change any settings I want.
