Error after installing on phpBB3

[michael plus]

Hello,

I`m getting this error after installing the chat on my phpBB3 forum:

This page contains the following errors:

error on line 102 at column 1: Extra content at the end of the document

Below is a rendering of the page up to the first error.

I can log in but its like i didn`t log in at all when i have logged in the chat is empty, shows no online users and doesnt display my messages.

Im hoping to have some help with this quickly because i need that chat soon.

Greetings,

Michael
