new accounts are not automatically added to the pre-moderated users list
I've just checked it with my local installation (and you could also test on the
miniBB demo), and I'm pretty sure the new profiles are automatically added to the Premoderated list, when having configuration similar to yours.
Try to check the code in
bb_plugins2.php, which is in response for this automatic addition. If you have Profiles Checker or Favorites add-ons installed, their code should be pasted after the code for Premoderation in this file. Else the Premoderation code should be the last before the closing ?>. Also make sure you have the proper code from the original installation package and most recent release of this add-on.

I see that the configuration menus show only the plugin's default, not my custom selections.
This indicates that the values are not saved to Database, and again, this is the reason to re-analyze the installation of this add-on step-by-step manually, following its README guides. I suppose, the problem is in some older or outdated file.
Your provider's server could restore some scripts of files if they are suddenly lost in the system, and the older copy could be taken - that's why it's always good to have a local copy of all fresh files for such a case.
If you fail on doing it yourself, you know my email address - drop me FTP infos and I'll take a look.
