Hello, I migrated from Debian packages xwiki 7.3 to 7.4 Since I have two errors: • when connecting, the connection is very very long. It loads after validation of login and password, and then it displays the dashboard. I do not see in the logs where it loses time. • when edtion of any page During validation, hiberntate sends me an error: Information détaillée: Error number 3201 in 3: Exception while saving document
