Here is the current footer of meta.stackexchange.com
and here is the current footer of the meta.stackexchange.com/users/login and meta.stackexchange.com/users/signup
The revision (or build) number on all of them shows as rev 2015.7.31.3625 and all of the three pages namely main page of Meta SE, the login page and the sign up page are currently residing under the same domain i.e. meta.stackexchange.com. So, how could the company name (Stack Exchange Inc v/s stack exchange inc) in the copyright footer gets mis-match? Are they pulled from the different files that stores the copyright? Can anyone please explain.
The company name was corrected on the most of the Stack Exchange Network sites in the yesterday's build and a status-completed was added by moderator Laura.
P.S:
Both of the pages i.e. "Login" and "Sign up" are part of this New year, new experiment: Login and Signup UI which went effect yesterday as per the post status of Upcoming login changes (Stage 2 and the new UI now LIVE).
