5 days ago I experienced a problem with my Behance account. All my projects became private and when I try to adjust the privacy settings, I can't find the drop-down menu that allows me to change my privacy, it's simply not there as I will show in the screenshots below.
I usually use firefox.
Another problem is that due to this privacy, my account isn't visible to anyone anymore, it's like my account got deleted. When I search my username's link on another browser, it says that the page is not found as I will also show in the screenshots.
I have no idea why this is suddenly happening and especially at a time when I sent out my portfolio for specific jobs that won't be able to find me now since I'm officially off the grid.
all three of your screenshots show the visibility dropdown set to private which is expected to make your website not accessible by others (Oops, we can't find that page). that visibility setting needs to be changed.
the capture shows somethng else.
if this answer fails to help you, explain what you're trying to show with, what appears to be, 3 identical screenshots and 1 capture.
