• I have a wordpress site which had wp version 4.9.18. The theme used here is a custom theme that uses Jquery [ jquery.js?ver=1.12.4 ] and [ jquery-migrate.min.js?ver=1.4.1 ].
    After I updated the wordpress version to 5.8.2, I got some issues with Theme customize section (it was displayed as blank). I reverted to version 5.6.6 and that particular customizer theme issue was resolved.

    Now, when I updated all the required plugins I could see some Javascript errors showing up in the browser console related to Jquery function as below ::

    Is there anything related to Jquery compatibility between the core updated wordpress and plugins.

    I have a wordpress site which had wp version 4.9.18. The theme used here is a custom theme

    First off, consider updating WordPress to the latest version.

    Second, If this was a custom theme, you may have to go back to your developer team and ask them to make the necessary change(s) to the theme. Commercial products are not supported in these forums.
