Using command /run leaplus() to configure options in game no longer works, and results in following error message. I understand that it's now /ltp, but it's very confusing because this command shouldn't even be enabled at all considering it's no longer valid.

Since the release of 10.0.5, /run leaplus() is no longer in the addon at all. The error message you are seeing is a generic game message telling you that the function does not exist. If you try /run tomhanks() you will get the same error message (other than it referring to tomhanks instead of leaplus).
