some strange behavior for anonymous

Hi,

The module works fine, but once I move in my site (using sky theme) some strange things happen. The links doesn't work anymore as links but provide me with the ajax content

{"user-online":{"content":"\u003cp\u003eThere is currently 1 user online.\u003c\/p\u003e\u003cdiv class=\"item-list\"\u003e\u003cul\u003e\u003cli class=\"even first last\"\u003e\u003cspan class=\"username\" xml:lang=\"\" about=\"\/user\/1\" typeof=\"sioc:UserAccount\" property=\"foaf:name\"\u003efleet-manager\u003c\/span\u003e\u003c\/li\u003e\u003c\/ul\u003e\u003c\/div\u003e","ajaxblocks_settings":""}}
