Which version of InDesign and OS?
Is it a reflowable text ePub?
Are you exporting to ePub 3?
What does it state when you validate your ePub?
Thanks. I am using InDesign 2015.2 with Windows 10. I am exporting to fixed layout ePub 3.
I have since gone back to the original file and made some adjustments to anchors and there are no errors popping up on export. I think part of my original problem was that I didn't exclude the final page which was the InDesign generated TOC. I don't know why exactly. My navigation is via Bookmarks and that is all working fine.
I validated (thanks for the tip) with the idpf online validator. The only error showing up when I validate is the following which I don't know how to find:
12 204 Error while parsing file 'value of attribute "src" is invalid; must be a URI'
Now I have a new issue. I viewed it in Chrome Readium (which is what I had the best luck with for the last issue--my first epub) and the body text is all garbled. It using a text style in Minion Pro (OTF) with no changes to this style since the last issue. Pages are also taking forever to load compared to last time.
What is the size of the ePub?
