I’m still waiting for an activation email for my new account at valorapps.com, so that I can “get” a fresh copy of the 2.7.8 package for comparison. (I don’t see a way to request a re-send.)
I see the questionable FILEINFO_MIME used in the easydiagnostic.php file, too, so if someone changed that constant, it was done consistently. It wasn’t me, but I’m not the original webmaster for our site.
