You must think you're awfully sneaky, eh?
We figured out the issue.. The JLinked - System plugin was set as "Registered" for the access level. Therefore, it simply wasn't executing if the user wasn't logged in.
That took a bit of poking around to finally notice. We added an admin key to both extensions, but you're free to change them however you want.
Hopefully, that gets you going, but if you run into other issues, just let us know. Also, please downgrade our user so we're no longer super admins.
Thanks,
Alex
