After migrating two separate v13 sites from v13 latest to v17.0, the sites seemed to be running fine for weeks. All of a sudden, the sites stop loading complaining about a missing column ‘isContainer’. As far as I understand it, this column was removed in v14.0. What could be causing this?
Any pointers would be greatly appreciated.
Welcome to the community, @tommot ,
I highly recommend checking your Umbraco trace logs (umbraco/Logs) from the exact minute the site crashed. The stack trace will show you exactly which assembly or package threw the missing column exception, immediately narrowing down whether it’s uSync, a custom query, or a core issue.
