TOPIC: request failed

I just installed joomlacomment and when i try to comment on an article as an administrator or a registered user, there is a "request failed" message when i'm on Firefox and a "only one top level element is allowed in a an XML document" message on Internet Explorer. But the message is still posted when i refresh the page. How can i remove these error messages popping up when there seems to be no error?

would you give us a link to your website? Did you install beta2?

www.miranada.net/www/nbfedm/awag/

here is the link.. and yes i installed beta 2. I tried to install the mmsblog component but it won't install because "Error: could not find XML setup file in the package".

would you make one account for me on your website so that I can test it?

actually i will just test the site more because i'm not even sure when this website is going up then when i am sure, i'll get back to you.

Thanks,
Natasha
