i installed freichat in wamp server working well.but when i installed on webserver it is not showing,
i changed gzip and ajax setting no to yes
still no change
pls check my website www.mcxwatch.in

You need to do a complete new install . If you have just copy pasted the files , it wont work.

i reinstalled twice but not working. no errors during installation.

now my site loading dns problem rectified, now i completely removed reinstalled joomla 3.1 and installed latest version 9.3 still same problem
when compared pages generated in localhost and server generated page.both are same but this line not there in body

It is still not loading , may be it will require some time for the change to have affect in our location .

our area my site www.mcxwath.in loading .when i compared in firebug this piece of html code not there in webserver generated page
id="friechtahtml">
div id="FREICHATXDATASTORAGE">

www.mcxwatch.in check chat not showing

The problem is that your server is injecting some unwanted javascript into freichat's script thus giving error .

The following is the unwanted piece of code being added to the end of freichat file
