    Hi there, @musasiug,

    Could you post your site URL here, so I can have a look?
    If you want to go ahead with the troubleshooting meanwhile, you could try purging any caches that you might have (WordPress cache, Cloudflare cache, etc) and trying to log into your site in an incognito window (to prevent browser cache from interfering) and try it out.

    If the above steps don’t change anything, can you take a screenshot of the DevTools Network tab and the Browser Console? Please make sure also to take a screenshot when you’re on the Jetpack Boost dashboard.

    You can create and share screenshots using something like Snipboard or Imgur and post the link here.

    Rest assured that we’ll run more tests at our end as soon as we have your site URL. Look forward to your reply!
