I already checked that the data config has a valid JSON, but I am still getting this error when I try to run my app. Here are the errors that I get: 2013-10-08 14:53:38.384 PrepCeneval[777:a0b] BT_application: ERROR parsing JSON in validateApplicationData: ( "Error Domain=org.brautaset.JSON.ErrorDomain Code=5 "Unescaped control character '0x9'" UserInfo=0xd302460 {NSLocalizedDescription=Unescaped control character '0x9'}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 "Object value expected for key: questionText" UserInfo=0xd3024a0 {NSUnderlyingError=0xd302480 "Unescaped control character '0x9'", NSLocalizedDescription=Object value expected for key: questionText}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 "Expected value while parsing array" UserInfo=0xd302600 {NSUnderlyingError=0xd3024c0 "Object value expected for key: questionText", NSLocalizedDescription=Expected value while parsing array}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 "Object value expected for key: childItems" UserInfo=0xd302640 {NSUnderlyingError=0xd302620 "Expected value while parsing array", NSLocalizedDescription=Object value expected for key: childItems}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 "Expected value while parsing array" UserInfo=0xd302390 {NSUnderlyingError=0xd302370 "Object value expected for key: childItems", NSLocalizedDescription=Expected value while parsing array}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 "Object value expected for key: BT_screens" UserInfo=0xd302350 {NSUnderlyingError=0xd3023b0 "Expected value while parsing array", NSLocalizedDescription=Object value expected for key: BT_screens}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 "Expected value while parsing array" UserInfo=0xd3022f0 {NSUnderlyingError=0xd3022d0 "Object value expected for key: BT_screens", NSLocalizedDescription=Expected value while parsing array}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 "Object value expected for key: BT_items" UserInfo=0xd302330 {NSUnderlyingError=0xd302310 "Expected value while parsing array", NSLocalizedDescription=Object value expected for key: BT_items}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 "Object value expected for key: BT_appConfig" UserInfo=0xd302230 {NSUnderlyingError=0xd302210 "Object value expected for key: BT_items", NSLocalizedDescription=Object value expected for key: BT_appConfig}" ) 2013-10-08 14:53:38.385 PrepCeneval[777:a0b] BT_application: validateApplicationData: ERROR: There was a problem parsing some configuration data.

@Edwin_raimond: Welcome to Buzztouch! Have you pasted your configuration data into this http://jsonlint.com? Jake

First -- Follow Jake's advice, check your JSON in the http://jsonLint.com web site. If JSONLint does not find any problem, then try this check: Download TextWrangler, it is a extremely useful text editor for the Mac. Make a new file. Copy-paste your JSON data into that new file within Text Wrangler. In the TEXT menu, select "Zap Gremlins" Tell it to delete everything and to delete the zapped characters. Tell it to Zap Then FILE menu, Close Document (CMD-W keys) If you are asked to "Save the changes", then it found some invisible characters in the JSON that was causing the 0x9 value to be inserted. Now comes the tough part, to find that 0x9 value. EDIT menu and undo the Zap. Do the ZAP again, but this time, tell it to insert the circle-character in place of the bad character. Then scroll through your file to find that location. You'll know into which Screen you had inserted that bad character through the Web Control Panel. Go into that screen and erase that field and re-type it all over again. Let us know how you get along! - Niraj

Thank you for your responses. I had checked the JSON in the json website before posting this question. Now I downloaded Text Wrangler and followed Niraj's instructions. I am creating a quiz in Spanish and it appears that all the stress marks are changed by Text Wrangler when looking for Gremlins... Does that mean that I have to eliminate all kinds of stress marks in my questions? Is there other way to fix this problem? I am trying to build a Spanish grammar and spelling quiz and it wouldn't make much sense if the quiz has spelling mistakes (no stress marks). Thanks again!
