The screen shot of the Extensions manager is not readable, I cant make out what extensions where installed.
Usually when you start getting errors about translators not being loaded, it means that the configuration folder has become corrupted. This usually happens as a result of installing a newer version of an extension without first uninstalling the previous version. renaming the configuration folder then reinstalling extensions is the best way to corrrect the problem.
With Security Assist 2, make sure it is the last extension installed since it is the newest.
