An incorrect structure was found in the pdf file

[flip!]

I am trying to move one page in the thumbnails view of a 16 page pdf. When I drag and drop the page I get this error:

"An incorrect structure was found in the pdf file" and it will not move the page.

What can I do to fix this without starting over?

I am using Adobe Acrobat Pro DC

Thanks

Tags are used so that Accessible Technology (AT) can make sense of them. People with disabilities rely on these tags to navigate through the document. An untagged document would be completely inaccessible.

If I had the original files I would have tried making a new binder but that wasn't an option in this case. 

You can also open the file in your Chrome browser and use their native "print to pdf" option omitting the trouble pages. That's what I did. Sorry Adobe.

I know this is a late reply, but this was the 1st post I found when looking for the same issue. All of the sudden, my Acrobat Pro has been throwing up that same error on this one document. I found 2 fast simple workarounds.

Workaround 1: Extract the page(s) you want, make sure to check the box "Delete Pages After Extracting". This will remove the pages from the PDF with the error. Then, from the new PDF that was just created, Click & Drag the page(s) back into the location you need.

Workaround 2: Rather than moving the page(s) - by clicking and dragging them, select the page(s) then hold the Control Key (CTRL) and copy them. Oddly enough, it lets me copy, but not move. Not sure why, but it worked. From there just delete the oringinal page(s) and you're good.
