They have an image of the http(s) authentication section showing a username and password in their respective fields.
I went there and see nothing. So I proceed to click on BOTH, leaving the fields blank, then click save. Once the page has saved, updated, and refreshed, I am looking at the same thing as before.
Well I checked a system without System Admin Pro, just the standard System Admin and “Provisioning Protocols” are not an option. So that answers my question.
I did test on a couple systems with Pro. Changing to “Both” or “HTTPS Only” and then hitting “Save” kept the default values in the fields and made them editable to be changed. So I’m not sure this is a bug per se just yet.
@GeekBoy What version of System Admin Pro are you running?
