I have lately got the privilege of protecting questions on Islam SE. Maybe I don't really know how this works, but i wonder, why on some questions i would get this opportunity as it is clearly displayed, while on other questions it isn't displayed at all:
For example here I can't even see the option to protect, even if the post is older than 24h.
While if i would like to protect this post. I could easily do so as the option is displayed.
I'd be glad if you could tell me whether this is a bug or not and why sometimes the "Button" appears and sometimes not.
