Hi. We have been troubleshooting an issue with IronPDF and the generated PDF not being valid. I have upgraded the dll to to latest version from NuGet. Does your license cover that or do we need to find another way around this or purchase a license for the solution.

You need your own license if you do any changes related to ironpdf or if you use the API directly.

What are you trouble shooting? IronPDF does not support flexbox and css grids (i.e. Bootstrap 4+5) in their current versions - we have had big issues with that. They have promised an upgrade in Q1 to fix that issue.

Hi Nicolai,

For some reason, when using www.biolegend.com as the URL, the pdf that is generated using the standard ironpdf.dll is corrupt. Any other subdomain works fine. An upgrade fixes that but has another issue. I'll have to get specifics but I believe we are just using new pdf command when generating it. The temp file that is stored on disk doesn't have the corruption. It only happens when the save button from a browser window is used.

Thanks,
Terri

Hi Nicolai,

Here is the URL that generates the pdf: https://www.biolegend.com/Default.aspx?ID=147&productid=15499&filename=Purified%20anti-Calnexin%20Antibody.pdf&pdfgen=true

And here is the validation URL that returns an error: PDF Tools Online - Validate PDF (pdf-online.com)

And here is the error that is returned:

Compliance pdf1.4
Result Document does not conform to PDF/A.
Details

Validating file "Purified anti-Calnexin Antibody (8).pdf" for conformance level pdf1.4

The "endobj" keyword is missing.

The "endobj" keyword is missing.

The document does not conform to the requested standard.

The file format (header, trailer, objects, xref, streams) is corrupted.

The document does not conform to the PDF 1.4 standard.

Done.

I cannot help you with that one...

The pdf looks fine here though.

pdfgen=true is not a Dynamicweb thing - must be something homemade.
