fifa mobile login failed 0x00

All the data comes from a database. Recently I've had a few issues with the error: Hexadecimal value 0x00 is a invalid character, line 1, position nnnnn. But its not consistent. Sometimes some 'blank' data will work. The 'faulty' data works on some PCs, but not others. In the database, the data is always a blank string. nordicbet login
