I have a problem when saving a PDF file. This error is always displayed in Acrobat Reader:

"This document enabled extended features in Adobe Acrobat Reader. 
The document has been changed since it was created and use of extended features is no longer available.
Please contact the author for the original version of this document."

Why is this warning showed and how do I turn it off?

I found it.

Debenu has method ".removeUsageRights()", that work.


"Remove the usage rights. This will result in a form that is no longer Reader enabled. 
For instance: if the creator of the document allowed that the filled out form could be saved locally, 
this will no longer be possible after removing the usage rights."

Hi Puty,

good to be able to help yourself ;-)
In an itext-forum this problem is explained very well:
https://itextpdf.com/en/resources/faq/technical-support/itext-5-legacy/why-do-i-get-error-saying-use-extended-features-no
With a RemoveUsageRights (after load):
https://www.debenu.com/docs/pdf_library_reference/RemoveUsageRights.php
and a new save you can avoid this ugly message.
Yes. This means that a form is no longer "reader enabled" but the reader is still able to work on the form ;-)

Cheers and welcome here,
Ingo
