UPDATE

Happily after testing around a lot this Error message isn't displayed anymore, unfortuatelly another appeared:

<NSHTTPURLResponse: 0x8b96d40> { URL: https://api.parse.com/1/classes/Workouts } { status code: 400, headers { "Access-Control-Allow-Origin" = "*"; "Access-Control-Request-Method" = "*"; "Cache-Control" = "no-cache"; Connection = "keep-alive"; "Content-Length" = 130; "Content-Type" = "application/json; charset=utf-8"; Date = "Wed, 30 Oct 2013 20:01:58 GMT"; Server = "nginx/1.4.2"; "Set-Cookie" = "_parse_session=BAh7BkkiD3Nlc3Npb25faWQGOgZFRiIlNjIxZjUxMzY3NWVhZWJmMDYyYWYwMGJiZTQ3MThmMWE%3D--851bd31b07e7dba2c5f83bb13a8d801ecbea42c4; domain=.parse.com; path=/; expires=Fri, 29-Nov-2013 20:01:58 GMT; secure; HttpOnly"; Status = "400 Bad Request"; "X-Runtime" = "0.060910"; "X-UA-Compatible" = "IE=Edge,chrome=1"; } } 

Can anyone tell me what the Status: 400 Bad Request is telling me and how I can get rid of it?
