While using tag like this:
<html xmlns="http://www.w3.org/1999/xhtml">
When we are on general Home (e.g. on 404) plugin replaces this line to
index.html xmlns="http:/www.w3.org/1999index.html">
so it become viewable on the top of page.
I think the problem is somewhere in unrigorous regexp in "multisite" plugin.
UPD:
I just localize the problem: this was happening when I haven’t domain specific 404 page, so modx go to default 404 page (from settings) AND on the general 404 page TV "host" is not specified. So regexp bugging.
Hence the question follows that which domain would I set in TV in general pages?
