Hi there!
I find a problem with SJ Live template with I try to use JSitemap Pro component from J!Extensions Store.
YT Framework plugin breaks the XML format of sitemap.
If anybody have the same problem - solution is here.

Tech.support from JSitemap find an error with SJ Live - there is forgotten extra check in /plugins/system/yt.php at line 163:
if($document->getType() !== 'html') { return; }

Details here:
storejextensions.org/forum/view/10-jsitemap/2944-re-error-in-xml-sitemap.html#2944

I suppose hope that Smatraddons team fixed this in the next version of YT Framework plugin.
