Confluence (5.7.4) System Error on AWS server
Asked by Dr. Andrzej Trembilski:

We have an old Confluence (5.7.4) server installation on AWS cloud. Needless to say - the guy who originally installed it, left our company last year. Some days ago the AWS server was switched off, now after reactivation we get a system error... . Is there anything we can do about it, at least to restore the text information saved in the database?

However it would probably be a good idea to [find a local Atlassian Solution Partner](https://partnerdirectory.atlassian.com/) that can help you with this. Also [Confluence 5.7 has long reached End Of Life](https://confluence.atlassian.com/support/atlassian-support-end-of-life-policy-201851003.html) so if you want to continue using Confluence you should upgrade to a newer version (for which a Atlassian Solution Partner would be helpful as well) or switch to Cloud. :)
