Error on exporting EPUB

[Golddonn]

I'm exporting a file as a reflowable epub and am getting this error message. "This is not a valid dimension. Aspect ratio not maintained when Width or Height is zero."  I've replaced all my images in the document and searched for empty text frames to no avail. Searched on the web for answers and found very little except for looking in the HTML for problems with classes. I would appreciate any help in resolving this issue.

How could the width or height be zero? Can you either post something for us to see? Otherwise please provide a few pages to download and try for ourselves. Thanks.

Thanks, Steve.

Thanks so much for the reply. Here is a screen shot of the error message.

I did validate the EPUB with idpf's validator, and it found no problems.

Presumably you’re exporting to ePub 3.

Which devices / apps have you viewed it on, and are there any issues that appear?

It might be worth spending $15 to get FlightDeck to validate (and more) your ePub:

Yes, I am exporting to EPUB 3. I've only viewed it in IBooks on my Mac so far, and I don't see any problems.

Thanks for the input on this problem. I did some testing and deleted 5 pages at a time until I found the offending page. Turns out there was a blank graphic on the page. I just happened to click on it and located it. Problem solved.
