Could not switch users

  • We have a perplexing situation with our staging version of the website….

    When one of our admins logs into WP-Admin and attempts to switch to another user they receive the message “Could not switch users”

    When I login to WP-Admin and attempt to switch users, everything works fine.

    The other admin can log into the live version of the site and switch users without issue.

    Both sites are using the same version of the “User Switch” plugin and both sites are using WordPress 5.9.2

    Working on the assumption that this is a caching / cookie issue, we have tried the following:

    • The other admin logged out, closed their browser and rebooted their computer before logging back in – Switching does not work
    • I logged in using the other admins credentials on my computer – Switching works fine
    • The other admin logged in with my credentials – Switching does not work
    • The other admin logged in on a different computer – Switching does not work
    • The other admin logged in using a private window – Switching works from the link on a users profile information but not using the link on the user list

    Any ideas?

    Did your other admin clear their cookies? Logging out, rebooting, etc doesn’t necessarily clear all (or in fact, many) of your cookies. I would ask them to clear their cookies for the domain in question and try again.

    The only way that switching to a user can really fail is if the user attempting to make the switch has a problem with their user permissions, and this could happen if there’s somehow other cookies having an unexpected effect. Also ask them to disable privacy extensions etc in their browser.

    While you’re at it you might try deactivating other plugins on your site in case one is unexpectedly messing with authentication.
