• When I’m logging into my dashboard and try to Add a new post, certain buttons are not working. My site was working fine yesterday, and I’ve made no changes or updates.

    If I click a button like Add Media… nothing happens. No pop up opens.

    I have the latest version of wordpress. I’ve enabled debug and that didn’t help.

    With debut enabled I found these errors:

    Any idea on where this issue is coming from.

  • Hi! Possibly update of your site was made for you by your hosting company (for instance).
    Check the version of WordPress. In the new release WordPress 5.5 there are changes related to the mentioned jQuery library. It looks like something else on your site isn’t compatible and needs to be updated as well (from its developer).

    If you have WordPress 5.5 now, see this list and try to install jQuery Migrate (it’s a temporary solution):
