    Hi there,

    Is anyone has already successfully updated a site using mPDF lib to PHP 8 ?
    I'm stick with this error : Fatal error: Trait "setasign\Fpdi\FpdiTrait" not found
    I've downloaded the latest version from there : https://github.com/mpdf/mpdf unzip it and uploaded the files in the right directory (/libraries/fabrik/vendor/mpdf/mpdf).
    The Fabrik files themselves have been updated from github on november the 12th
    Joomla version : 3.10.11
    PHP version : 8.1.0

    Thanks for any advice

    Did you try to take it from Fabrik4? I did not test. But in Fabrik4 mPDF is working.

    I've just tried but I get the same result.
    I've renamed original mpdf folder to mpdf_original and copied the whole content of the mpdf directory from a J4 site to my test site on /libraries/fabrik/vendor/mpdf/ .

    My original test was from a php cron script.
    So I set pdf icon on a usual frontend list rendering (working on the production site under PHP 7.4) and I get the same error (pure Fabrik's code) :
    Fatal error: Trait "setasign\Fpdi\FpdiTrait" not found in /home/bishlws/examulmtest/libraries/fabrik/vendor/mpdf/mpdf/src/FpdiTrait.php on line 25

    I've also copied the domPDF directory from J4 to my J3 test site and I get :

    Class "Masterminds\HTML5" not found /zzzz/xxxx/yyyyyy/libraries/fabrik/vendor/dompdf/dompdf/src/Dompdf.php:477

    So I finally let it work.
    Here is my setup :

    replace the mpdf files in /libraries/fabrik/vendor/mpdf/ with the ones used for Fabrik 4 (last version of mpdf ?)
    replace the fpdi files in /libraries/fabrik/vendor/setasign/ with the ones used for Fabrik 4 (the ones found here : https://github.com/Setasign/FPDI ?)

    I did not find the right place to make the fpdi classes loaded by fabrik. So I've edited the file : /libraries/fabrik/vendor/mpdf/mpdf/src/FpdiTrait.php to add the " fpdi autoload" :

    Code (Text):
    <?php

    namespace Mpdf;

    include_once JPATH_LIBRARIES . '/fabrik/vendor/setasign/fpdi/src/autoload.php';   // added line !

    use setasign\Fpdi\PdfParser\CrossReference\CrossReferenceException;
    use setasign\Fpdi\PdfParser\Filter\AsciiHex;
    etc...
     
    And it works....
