THIS MAY OR MAY NOT AFFECT various v1.5.0 implementations. We're posting it here "in case". Implementing this fix is safe either way.

Symptom: Admin Login "broken" in v1.5.0 - v1.5.5a with Google Chrome error: "Aw, snap"


Google Chrome 54.0.2840.59 is now forcefully disallowing the use of javascript function declarations of 'animate'. This interferes with the "spinner" that appears during admin login since v1.5.0


The fix is simple:
1. Open /admin/login.php in a code-safe text editor, such as Sublime Text:
2. Find and replace "animate(" with "waiting_spinner(". There will be 3 occurrences.
3. Save
That's it. Login should now work again.
