I just unboxed my new ER-X-SFP-US, and after accepting the terms and entering the default creds, I see a loading bar for about half a second, and then:
Fatal Error Unable to load the router configuration
Digging a bit shows that /api/edge/get.json is throwing a php error (even though it returns HTTP 200!):
Fatal error: Cannot redeclare class UBNT\Core\Api in /var/www/php/core/classes/api.php on line 14
Which looks similar to the problem in this post except I haven't made any customizations, since I haven't even logged in successfully at this point. I've tried resetting the router to factory settings too, but that seems kind of redundant, since the factory settings are what caused the problem. Power cycling the router didn't give me any different (magical) results either.
Help?
