Fatal error: Undefined constant FS_CHMOD_FILE when printing

    Hi,

    I’m getting a recurring fatal error when printing via:

    /wp-admin/admin-ajax.php?print-order=XXX&print-order-type=packingslip&action=print_order

    PHP Fatal error: Uncaught Error: Undefined constant "Tyche\WCDN\Services\FS_CHMOD_FILE" in .../includes/services/class-pdf.php:427

    Plugin version: 7.2.0
    WordPress version: 7.0
    PHP version: 8.3.31

    Likely cause: it seems that wp-admin/includes/file.php which defines the constant isn’t always loaded during an admin-ajax.php request.

    The issue may be related to the fact that FS_METHOD is set to ssh2 rather than direct in my setup (however, ssh2 works perfectly in other cases like updating or installing plugins and so on). The issue also appeared with recent versions of the plugin while it worked fine for several years before. Unfortunately, I don’t know which exact version of the plugin started the issue.

    Thanks for looking into it.

    Hi @mkrause,

    Thank you for the update.

    I tried replicating the issue on our staging site, but I was unable to reproduce it. I tested printing packing slips as well as other document types, and no errors were generated during testing.

    Could you please share screenshots of your Print Invoice & Delivery Notes plugin settings? This will help me configure our staging site similarly to yours and attempt to reproduce the issue under the same conditions.

    I look forward to your reply.
