Removal of all user from the journal

I am using OJS 2.4.8.1 and all the user were suddenly deleted from the journal website. The author name are available in the archives but now user is showing in journal. I have checked mysql Database and all the information is available in it. Any suggestion to resolve the issue?.

Hi @sciplatform,

Can you clarify where the users are missing?
