TOC attribute validation error

[curiousgeorge]

I have a validation error I am curious to know what it means.

Error:

<Error>
  <Message>toc attribute references resource with non-NCX mime type; "application/x-dtbncx+xml" is expected</Message> 
  <Line>67</Line> 
  <Resource>OPS/package.opf</Resource> 
  <Class>com.adobe.common.ReportElement</Class> 
  </Error>

When i check the area for the package,ocf in regards to the spine on line 67:

<spine toc="ncx">
<itemref idref="html-cover-page" linear="no"/>
<itemref idref="frontmatter01"/>
<itemref idref="title"/>
<itemref idref="copyright"/>
<itemref idref="dedication"/>
<itemref idref="contents"/>
<itemref idref="frontmatter02"/>
<itemref idref="frontmatter03"/>
<itemref idref="frontmatter04"/>
<itemref idref="part01"/>
<itemref idref="frontmatter05"/>
<itemref idref="part01chapter01"/>
<itemref idref="part02"/>
<itemref idref="part02chapter02"/>
<itemref idref="part02chapter03"/>
<itemref idref="part02chapter04"/>
<itemref idref="part02chapter05"/>
<itemref idref="part02chapter06"/>
<itemref idref="part02chapter07"/>
<itemref idref="part02chapter08"/>
<itemref idref="part02chapter09"/>
<itemref idref="part03"/>
<itemref idref="part03chapter10"/>
<itemref idref="part03chapter11"/>
<itemref idref="backmatter01"/>
<itemref idref="backmatter02"/>
<itemref idref="backmatter03"/>
</spine>

found it. in the manifest it was calling for an incorrect ncx file here:

<item id="ncx" href="toc.ncx" media-type="application/xhtml+xml"/>

media-type was wrong and changed to:

<item id="ncx" href="toc.ncx" media-type="application/x-dtbncx+xml"/>

Thank you! I'm so glad I have this website to come to when things like this pop up! We're uploading old, old, old (2009 produced) ebooks and they fail current validations. I have to open the epubs in Sigil's current version, run epupcheck, and I got this error! I knew there had to be SOMEONE out there who came across this before. THANK YOU!
