EPUB Export: Pages Displaying Right to Left Instead of Left to Right

The solution for this is to search for RTL characters in your file. @Joel Cherney helped me with this when ALL the other solutions in this thread were incorrect, even from Adobe staff! 😞 Once RTL characters are removed, page order reverts to normal.

To search for Arabic/Hebrew etc characters, go to SEARCH > FIND FORMAT > ADVANCED CHARACTER FORMAT > LANGUAGE and pick any RTL left languages you may have introduced. Replace all with ENGLISH Language (click on CHANGE FORMAT in SEARCH and pick ENGLISH in Language to replace).

Hope this helps.

You must be using the MEL edition of InDesign, or the book files were created on one. That version is the only one I know of that allows RTL-LTR page order switching.

If the component files are set up LTR (standard Western language flow) and the reversal happens only in the Book export, look through the latter for a page direction setting. (Don't have/don't work wtih the Arabic/Farsi/Hebrew version, so I can't check.)

Worst case — delete the Book and recreate it.

If the component files are RTL, you will need to fix them to solve the problem

Hi @SamLC,

Thank you for bringing this issue to our attention! I can understand how confusing it must be to have your EPUB pages displaying in the wrong direction. 

To assist you better, could you please let me know which version of InDesign you are currently using and the operating system details? Additionally, is this issue occurring with just one specific book file, or have you noticed it happening with multiple files as well?

If possible, could you share a screen recording that shows the InDesign document frames followed by the EPUB pages? This will help us understand the situation more clearly.

In the meantime, a common solution for this issue is to check the "Document Setup" in InDesign. Ensure that the page layout is set to "Left to Right" under the "Text Direction" settings. Sometimes, when exporting an entire book, InDesign might inherit settings from one of the documents that could lead to this unexpected behavior. 

I appreciate your patience, and I look forward to your reply with the additional details so we can get to the bottom of this!

Best,
