PDF file format exports blank pages

I am using an old licensed version of Aspose Tasks (version 18.12.0) with a 2022 version of Adobe Reader to generate and open PDF documents in a browser (such as Chrome).

Recently the PDF exports generated using Aspose Tasks are now generating in the browser with blank pages and without any of the expected or intended content within.

Is this a known limitation of using an old version of Aspose Tasks with a more recent version of Adobe Reader?

Is my Aspose Tasks version now incompatible with recent versions of Adobe Reader?

Or could it be something else that I might not be aware of?

@lheslop,
I converted an arbitrary MPP file to PDF using 18.12 and opened it using Adobe Reader v. 2022.003.20282, 64 bit version and it looks OK.

It’s hard to diagnose further without the details of issue in the form of used sample code and source file.

Have you tried to open the resulting PDF using stand-alone version of Adobe Reader?

We don’t know about such limitations.
