I see only a small part of orca script, other one is being displayed just as code. Firefox console gives error: Selector expected. Ruleset ignored due to bad selector. Opera gives same as well, error: XSLT - http://www..../groups/orca/layout/uni/xsl/forum_topics.xsl
start-tag at line 13, column 67
Error: invalid use of disable-output-escaping='yes'
Solved, installed xml.
