I have completed an upgrade from 4 to 4.52 and set the <UseLegacyXmlSchema>true</UseLegacyXmlSchema>. I also republished the entire site. However, none of my xslt work stil. I've supplied one of my xslt's below that I use for a footer navigation. There is not error in xslt below, it just is empty. If anyone has any ideas let me know. I had not planned to have to update all my xslt with this upgrade and instead to do it over time, but right now I would spend the time to rewrite it if that work. Thanks for any help!
