I am unable to synchronise a document with several forms. I get the message:
Synchronization has failed
Error sending to server.: Invalid attachment data for icon, 400
Searching previous forum items, I see that this might be an invalid form icon. I have tried changing some icons, without it making any difference. I then removed all form icons (replacing them with the blank icon in the top left hand corner of the drop-down selection box). Again – I get the same result.
