    My site has this fatal error when navigating to a Module in the navigation links at the bottom of a Lesson. What is the resolution please? I’m going to launch my course on Tuesday. Thanks.

    Fatal error: Uncaught TypeError: Argument 2 passed to Sensei_PostTypes::lesson_is_protected() must be an instance of WP_Post, null given, called in /var/www/wp-includes/class-wp-hook.php on line 287 and defined in /var/www/wp-content/plugins/sensei-lms/includes/class-sensei-posttypes.php:174 Stack trace: #0 /var/www/wp-includes/class-wp-hook.php(287): Sensei_PostTypes->lesson_is_protected(false, NULL) #1 /var/www/wp-includes/plugin.php(212): WP_Hook->apply_filters(false, Array) #2 /var/www/wp-includes/post-template.php(854): apply_filters('post_password_r...', false, NULL) #3 /var/www/wp-includes/post-template.php(520): post_password_required(NULL) #4 /var/www/wp-includes/post-template.php(459): get_post_class(Array, NULL) #5 /var/www/wp-content/themes/primer/content-page.php(13): post_class() #6 /var/www/wp-includes/template.php(732): require('/var/www/wp-con...') #7 /var/www/wp-includes/template.php(676): load_template('/var/www/wp-con...', false, Array) #8 /var/www/wp-includes/general-template.php(204): locate_template in /var/www/wp-content/plugins/sensei-lms/includes/class-sensei-posttypes.php on line 174

    Hi @laurareturner

    I’m sorry for the delay in responding here!

    If you’re still getting this error, I’d make sure that your site: WordPress, plugins, theme – are all up to date.

    Next, if you’re still seeing the error, make sure it isn’t a plugin or theme conflict.

    Try disabling all of your plugins except Sensei LMS (and extensions). Then try testing again to see if the issue persists. If that resolves your issue, you can find what was causing it by enabling each plugin one by one while continuing to test.

    If that doesn’t help, you can also try switching to the Twenty Twenty theme via Appearance > Themes, and test again. If the issue is resolved then you know it’s a problem with the theme, and you’ll need to contact the theme author for further assistance.

    If neither of those help, could you try the following steps so we can find out more about the problem?

    1. Open the page which displays the error.
    2. Open your browser console by following this guide: https://ww.wp.xz.cn/support/article/using-your-browser-to-diagnose-javascript-errors/#step-3-diagnosis
    3. Click on the Network tab
    4. Refresh the page.
    5. Try to use the module navigation.
    6. If you see any lines in red inside the browser console, click on them. A new panel should appear on the right.
    7. Click on the “Response” tab in that new panel.
    8. Copy the message displayed there.
    9. Paste it in a reply here.
    10. If no red lines appeared in the browser console, click on the “Console” tab of the browser console.
    11. Copy any errors displayed there, and send them back to me.

    Best,
