    I am experiencing jQuery errors in the Dashboard and the plugin Enable jQuery Migrate Helper did not help. When I try to edit a post or page I get in the console:

    Uncaught TypeError: Cannot read property 'interval' of undefined
        at n (wp-auth-check.min.js:2)
        at HTMLDocument.<anonymous> (wp-auth-check.min.js:2)
        at HTMLDocument.dispatch (jquery.js:1)
        at HTMLDocument.r.handle (jquery.js:1)
        at Object.trigger (jquery.js:1)
        at Object.jQuery.event.trigger (jquery-migrate-1.4.1-wp.js:54)
        at HTMLDocument.<anonymous> (jquery.js:1)
        at Function.each (jquery.js:1)
        at jQuery.fn.init.each (jquery.js:1)
        at jQuery.fn.init.trigger (jquery.js:1)

    I am not allowed to switch from the Text to Visual Tabs in the editor, we are using Classic Editor.
