Editing an existing data source may result in some cases to a security-releated error (e.g. It is forbidden to use server files). A fix will be available in the next release, but if you encounter this error using this release, you can try one of the following workarounds:
- Set the configuration option allowed_server_path_directories in the section data_load of the /etc/squirro/common.ini file to /var/lib/squirro/temp and then restart the datasource service (systemctl restart sqdatasourced).
- Delete the data source and recreate it.

You will have to resolve at least the following config files when upgrading from Squirro 3.3.0
