I'm having the same issue. Can't login to Zymurgy app on my iPad or Android phone. Can't login to the AHA website either. When I try logging into the website I get
The requested URL /wp-content/themes/aha2016/includes/proc_login.php was not found on this server.
I tried changing my password and that didn't work either. Normally you get a confirmation saying "Password successfully changed" or something like that, but when I tried it, it literally did nothing. Didn't even refresh the page.
