Uncaught TypeError after update

  • After updating from v3.2.8.6 to v4.1.6 after a Security Vulnerability warning from our host. We receive the following JS Console Error, when we click the Purchase Course button.

    single-course.js?ver=6232d70eefbce:1080 Uncaught TypeError: Cannot read properties of null (reading ‘classList’) at HTMLFormElement.<anonymous> (single-course.js?ver=6232d70eefbce:1080:13).

    Any help would be appreciated.

    I made two attempts to update the site. First attempted and then rolled back the site to the original state. In both cases, all plugins were updated and all database updates were completed. Both resulted in the same error.

    Hi,

    We see your site change our template so JS can’t run.
    For example, the Purchase Course button doesn’t have the CSS class “button-purchase-course” so that is the cause of the problem.

    Thanks

    Yes, thank you, that fixed the issue. That would have taken an eternity to find.
