We have a SharePoint 2010 feature that works fine on my development machine, but won't activate on the staging system. It's SiteCollection scoped, the containing solution was successfully deployed on one WebApplication.
When we try to activate the feature, we get an error message with a Correlation ID. But we can't find this ID or the name of the feature in the SharePoint Logs nor in the Windows Event Log.
Maybe logging wasn't configured right or there is an error with ULS on the machine, but we haven't changed the SharePoint Logging options from the state they were after installation. Where can I find exception / error messages that happen in ULS? How must Logging be configured to allow the failed feature activation to be logged?
