* FreeWPress,
* Is this causing issues on your site? Also, do you know where the first xmlns=”
[http://www.w3.org/1999/xhtml”](http://www.w3.org/1999/xhtml”); is
coming from, or if it is being provided by the language_attributes filter? What
is your theme?

* FreeWPress,
* I’d suggest removing the xmlns=”[http://www.w3.org/1999/xhtml”](http://www.w3.org/1999/xhtml”);
from the header, then. Because it’s not output by language_attributes(), there’s
no way to filter it, or for the plugin to know it’s there. See [the example here](http://codex.wordpress.org/Function_Reference/language_attributes#Examples)
for reference.
