First of all hello to all! I greatly appreciate the privilege of being a new member to this forum.

My question is what does the following epub error mean?

BK00017800.epub/OEBPS/content.opf(159,60): hyperlink to resource outside spine 'OEBPS/toc.xhtml'

Can anyone please let me know if this has a simple solution. I'm trying to get my novel's epub file wider distribution through a company, and although the file did pass the standard beta validator checker, it failed the distribution company's check with this one error. It is already up on Amazon Kindle with no problems.

Any feedback is greatly appreciated.

Many thanks in advance!
