Q:

Unable to approve user registrations via email link

Since the latest update of Joomla I can no longer approve a user via the link in the registration approval email.  

As of 3.8.13, Joomla is securing the process on approving an user after an email notification by requesting the administrator, who is going to approve the request, to login into the frontend. After the administrator logged in, they are redirected to the activation URL and the account is activated. 

However this does not work. I click the link and get the message: 
Please log in to confirm that you are authorised to activate new accounts. 
When I then log in as Super User I get the message: 
You are not authorised to view this resource 
and the user remains unapproved. 
Any suggestions as to how to get around this issue? 

A:

I think I have discovered my issue. It appears to be due to ACL (access level) for the login menu item. It has to be public.
I followed the steps for the first answer in this post  and now it works perfectly.
