[xwiki-users] Annotations feature not working

Hello folks, I've installed the latest XWiki Enterprise2.3 ML1 and this is a fresh install. However, ran into difficulties with the annotation feature. When I save an annotation using the "Add Annotation" feature, the annotations do not get saved. There is no symbol that is generated next to the text that I was trying to annotate. Also, I get an error at the bottom of the Page which states: No Host matches server name localhost I used the firebug plugin to find out what events were getting fired. Following is the stack trace: POST: http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/Main/pages/WebHome/anno… Code: 400 No Host matches server name localhost localhost:8080 Server Apache-Coyote/1.1 Transfer-Encoding chunked Date Fri, 26 Mar 2010 06:09:39 GMT Connection close Request Headersview source Host localhost:8080 User-Agent Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.9.1.8) Gecko/20100202 Firefox/3.5.8 Accept text/javascript, text/html, application/xml, text/xml, */* Accept-Language en-us,en;q=0.5 Accept-Encoding gzip,deflate Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive 300 Connection keep-alive X-Requested-With XMLHttpRequest X-Prototype-Version 1.6.1 Content-Type application/x-www-form-urlencoded; charset=UTF-8 Referer http://localhost:8080/molecule/bin/view/Main/ Content-Length 275 Cookie username=obD1aIklU0E_; password=FS1YvSKKiX8_; rememberme=false; validation=12faf980e85d2f5a1216a4c7e320a4bd Pragma no-cache Cache-Control no-cache Parameters application/x-www-form-urlencoded annotation help author XWiki.Admin date Fri Mar 26 01:32:31 EDT 2010 selection WebHome selectionContext WebHome selectionOffset 0 Source selectionOffset=0&selectionContext=WebHome&selection=WebHome&date=Fri%20Mar%2026%2001%3A32%3A31%20EDT%202010&author=XWiki.Admin&annotation=help XML Parsing Error: no element found Location: moz-nullprincipal:{833f3ffa-8712-4980-aff7-a4aabf47426e} Line Number 1, Column 1:
