Not compatible with PHP 8.x

  • unfortunately this plugin uses an 11 year old library, which will result in a Call to undefined function get_magic_quotes_runtime() error.

    Can you specify which library you are referring to?

    I’d say this is not much of an issue since upgrading to PHP 8.0 is somewhat experimental right now – and I did expect some plugins to fail.

    Nevertheless, you’re using PDFMerger (from December 2009), and more specifically the FPDF class it brings, did fail with PHP8.

    I resolved this by switching from that library to Ghostscript (via command line).
