At our company we run Filemaker Server 15 hosted locally.
The company runs Filemaker 15 on their macs. I have 15 and 16 on my Mac to test it.
All has been going well until today. Filemaker 16 has three instances "field missing" in one table.
Filemaker 15 displays everything as it was.
In 16 I can not even access the fields as they greyed out and say "Unknown"
Any ideas on why this has happened - a bit worrying!
