New Forum Topic - Error

Hey

When I try and create a new forum topic on my site I receive lots of errors like this:

Warning: XSLTProcessor::importStylesheet() [xsltprocessor.importstylesheet]: :xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/1999/xhtml" in/******/modules/boonex/forum/classes/en/BxXslTransform.php on line 69

Any idea how to fix?

It looks like a typo in XSL template:

Recompile forum languages after the change.
