My server(VM) was running for long and users were using the system.
Yesterday, after rebooting of the server (VM and Physical both), “Internal Server Error” was appearing.
Then I found that “developer_mode”:1 was commented (by //) in the common_site_config.json. After uncomment of this, the server is getting access.
However, I do not see the users data. It is showing my initial setup data along with some data imported by Data Import Tool.
Please advice, what happened and how to get back all data.
