hi
i set up freichat yesterday and try it out.
So i have to issues.
First the counter on the web site says i have two guests but they doesn´t appear in the chat.
Second i try to send a file and it says susscessful send to 4, but nighter at my friend or me arrived the file. Where i can find them and what can be the problem. I'm sure that i made something wrong in the settings of the chat :) so far a nice and easy chat system.

FreiChat removes any inactive users, so your website counter must be showing inactive users too .

Second i try to send a file and it says susscessful send to 4, but nighter at my friend or me arrived the file

Check if the files are actually getting uploaded in freichat/client/plugins/upload/upload .
chmod the above directory to 0777

found them now but we are not able to see it in the chat room

So, do you mean it is working in the private chat ? or not working in both ?

Did you chmod the directory to 0777 ? And are you getting any errors in browser console while sending file.
