Confluence had problems starting up

Upgrade failed. Please consult the system logs for details. You will need to fix these problems, restore your database and confluence home directory to the pre upgrade state. Then retry the upgrade. Upgrade error message: Upgrade task com.atlassian.confluence.upgrade.upgradetask.DenormalisedSpacePermissionsUpgradeTask@6bb55584 failed during the SCHEMA_UPGRADE phase due to: StatementCallback; bad SQL grammar [DROP TRIGGER IF EXISTS denormalised_space_permission_trigger]; nested exception is com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near the keyword 'IF'.

Hi @insistdoo 

Probably you hit this reported bug: CONFSERVER-61145

Is your database version compatible with your Confluence version?  Here is the link to check that 

If your database version is not on the supported list you won't be able to upgrade successfully. Please check the issue!
