Error SQL query: Edit SET CHARACTER SET 'utf8'; MySQL said: Documentation #1045 - Access denied for user 'root'@'localhost' (using password: NO)
Have you been sorted on this. Some database setting sometimes require you to have a password set for the root user, so that will be my first place to check.
@arnek For this settings, this is not required. But you must have correct password for root. Can you login to MySQL with usename root and empty password with any GUI tool/command line?
