Steps to reproduce:
- Open the navigation drawer and select All Sites option, it will show you all the Stack Exchange sites.
- Select any site in which you haven't logged in yet (i.e., you are not member yet). For example, I have selected Arqade. As we have selected Arqade, it will load all the questions of this site.
- Select any Question and navigate to Answer section.
- Now try to post answer, it will give you below error message:
Here user can post answer on any question on any Stack Exchange site. It should show me login page for the site which I haven't joined yet or simply it shouldn't allow me to post on that particular Stack Exchange site which I haven't joined yet.
As I have mentioned in 1st point it allows users to post answer on any site but I know the answer never going to be get posted on that particular site. Here it should show proper error message then. You can see improper error message "this error has been logged" by which no user can come to know what is the error exactly.
