Error in content.opf causes ebook editor checking to fail

[SteveB]

Thanks for your responses to other things much appreciated
I thought I'd report this in case it's helpful

If I make a mistake in content.opf manifest, run checks in ebook editor falls over
For example (notice the item paths where I got confused)

<?xml version='1.0' encoding='utf-8'?>
<package xmlns="http://www.idpf.org/2007/opf" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:dcterms="http://purl.org/dc/terms/" xmlns:opf="http://www.idpf.org/2007/opf" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" unique-identifier="67afb23f-0b1a-4a1d-aaa7-40cf4f5285a6" version="2.0">

  </metadata>
    <manifest>
    <item href="Text/test.xhtml" id="id7" media-type="application/xhtml+xml"/>
    <item href="/fonts/Times-New-Roman.ttf" id="font1" media-type="application/x-font-truetype"/>
    <item href="/Styles/fonts.css" id="font_embed1" media-type="text/css"/>
    <item href="/Styles/styles.css" id="id13" media-type="text/css"/>
  </manifest>
  <spine>
    <itemref idref="id7"/>
  </spine>
  <guide>
  </guide>
</package>

Here is output
