    Hi @bluesix

    That’s unusual, as the function is indeed present in the Helper function. It’s possible that another plugin you’re running simultaneously includes a different version of the Dompdf library. Many of these plugins also generate PDFs, which could be causing the conflict.

    Let us know.

    Ah thanks for the tip! I looked into it – the conflict was with Formidable Forms PDF add-on. All sorted now!
