Menu bar does not work after upgrading wordpress

  • After upgrading to wordpress 5.6, I cannot access the menubar properly. If I click on a menu, the drop down list does not appear. In the browser console, I get the following error:

    Uncaught Error: Bootstrap’s JavaScript requires at least jQuery v1.9.1 but less than v3.0.0
    at theme.min.js?ver=0.4.4:3
    at theme.min.js?ver=0.4.4:3

    I installed the jquery migrate plugin. If I set the jquery version to default wordpress, the drop down list in the menu bar does not work. But, if I set it to legacy version, it works. But, the plugin does not show any logged deprecations. Please help.

  • I can’t help you specifically… but I just wanted to report that…

    5.6 works on my own sites and dozens of client sites I manage… with ZERO issues.

    So this is most definitely an incompatibility issue with your theme or some plugin… whatever is loading Bootstrap (I may be wrong: but I don’t remember WordPress shipping Bootstrap in previous versions).

    You may want to use the Site Health plugin’s Troubleshooter to disable all plugins and switch to the default theme, and enable them one after the other to see what triggers the problem (using the plugin ensures this will only affect your logged-in session behind the scenes.)

    Thanks a lot @george. I could figure out the conflict with the troubleshoot plugin.

    Hi @userpqr I have the same problem, drop down menus not working. How did you manage to fix it please?

    Hi @ajphoto For me it is a conflict between the theme and wordpress. I installed Enable jQuery Migrate Helper plugin and set the Jquery version to legacy in the settings. It helps for the time being till the actual issue is resolved.

    great! I am going to try the same!
    Thank you for that prompt reply.
    Regards to you

    @userpqr, it worked!!! Excellent.

    So this means we have to wait until there is a wordpress update/fix, correct?

    Hi @ajphoto This does not seem to be a problem with WordPress. You may have some conflicts with your existing theme or some plugin. You may want to disable all the plugins and/or change the theme and figure out what plugin or theme is causing the problem. That plugin or theme needs to be updated as per my understanding.

    ok thanks for explaining, much appreciated

    @userpqr you saved me from a heart attack.
    Indeed after update, all menus stopped working.
    I installed Enable jQuery Migrate Helper plugin as you suggested and set the Jquery version to legacy. For the time being, menus work again as they used, so we have time to find if theme or some plugin is causing the issue.
    At least we don’t have to revert to the latest backup.

    Thanx again!
