      This usually means something wrong or unexpected in the details of a user, preventing the javascript that creates the list from functioning.

      If you follow the link in the error message you will find details about how to look for it.
      If that doesn’t help, set up an admin account I can use on your site, send me the details, and I will look at it tomorrow.

      Thanks Ole, login details received.

      Now I can see the problem. Just as well you gave me access as it is not what I first suggested. Thankfully I have seen this before.

      The actual problem, once you get past the error displayed is “403 Forbidden – Access to this resource on the server is denied!

      Your web host has recently enabled or updated “mod_security” with a rule that does not like “admin_user.php”. It assumes such a word is an attempted hack into the system. I see that your version of LiteSpeed Web Server was updated on 1st March 2018, so that is when the problem would start. It is an unfortunate coincidence that kiwitrees was also updated around the same time.

      Here is another example on the web about this issue:

      Contact your web host about this. It is not a bug in any system, just a rule that needs adjusting slightly by them. They should be able to find a reference to it at their end on the mod_security logs. If it helps, the URL causing the problem, coming from kiwitrees is:
