I thought I’d try out Invisible Mode in Edit Options. I ticked the box for that mode, changed nothing else, then scrolled down and clicked Save Changes. The following message was the result.
Mystified I thought I’d goofed somehow so I repeated the process with great care several times, all with the same result. Isn’t Invisible Mode supported any longer on the board?
I just went through this exercise and had the same result as the OP the first time through. Second time through, I saw that this whole s t r a i g h t business is a verification field to be used when making changes in the CP. It’s probably always there for any sort of changes in the CP, but it’s new to me since I seldom go into CP. Anyway, I think aldiboronti is probably not noticing that this field needs to be filled in before saving CP changes to be successful. The error message for failing to do so isn’t clear to my mind.
Huh, went back to make myself visible again, and this verification requirement is not there any longer for me. So now I’m guessing it is a one-time thing that aldiboronti and I had yet to encounter, and that Cochrane probably dealt with long ago.
