Answer
If you are receiving an 'Invalid XML Error' when attempting to submit your Single Touch, it usually means that there is an issue with the personal information of the employee named in the error message.
Examples of this include the employee's address being more than 38 characters long or otherwise a non-standard character in the employee's name (such as ö or é).
If you're not able to identify the issue, please go to Settings > Backups and click Send Backup to Support. Please include a brief description of the error. Once you have sent the backup, please give our support team a call on 07 3051 5895.
