Hi ,

I've a problem, ater upgrading from mariadb 10.0 to the latest version some of websites on the server doesn't work and gives this error

This error appears in many websites running on the server and i don't know what i should do to fix this?

Error establishing a database connection

You are getting this error because websites unable to establish a database connection or database has been corrupted.
1) Please make sure MySQL service is running on the server.
2) Please check MySQL error logs while getting this error.

Hello,

Could you let us know the recent output to /var/lib/mysql/$hostname.err? You can use a command such as:

tail -300 /var/lib/mysql/$hostname.err

Replace "$hostname" with your server's hostname.

Thank you.
