Won't work for 000webhost but works on XAMPP.
Trying to integrate into phpBB3
Need help.

Changed the server. But now it displays. BUT YOU CAN'T DO ANYTHING! You can't chat and it always says loading...

probably your host is adding unwanted javascript code, you should let me know the URL,
we had a lot of people having trouble with free webhosts.

It works now. Odd. Why does it interfere?

The host adds unwanted script in the AJAX response ,
and since FreiChatX uses JSON , any unwanted characters
can cause problems since it is the unable to decode it .
