Combine PDFs tool makes a PDF that is unable to be opened by others

[Karim12]

Hey guys,

Just tried to combine a couple PDF files earlier and it worked fine, however when I opened the file in Chrome, it came up with this odd pop up (below). I was really confused as I just combined a few files the other day and it was fine. Anyone know why this happens/how to fix it? 

Cheers

Nothing is wrong (though it's still annoying). You combined the files into something called a "portfolio". Chrome has no clue what to do with it, so you see this message. Web browsers are limited for viewing PDFs. Just download it, and open it in Acrobat Reader. If you want to avoid the issue, look closely at the settings when combining the files, and turn off "portfolio". Important note: DON'T turn off portfolio if you are combining fill-in forms!
