I' had used Admin Backup/Transfer for restoring after that it's show 0B all site is working ok but when I check on /var/lib/mysql/xen_data... don't have any database on that locationHave you tried optimizing or repairing the database?
Have you checked file ownership comparing this user to others?
Do the databases work?
/var/lib/mysql/xen_data... meanWhere is the database located?
Where are the databases that do work?
What makes you think that you should be checking for /var/lib/mysql/xen_data? There's no database by that name in your attached image.
I'm using centos 6 64bit i'm sure that right path of mysql database because I can see all data on that /var/lib/mysql/* I try to login into phpmyadmin by use that include data:You mean that does folders doesnt exist?
Does the /var/lib/mysql folder exist? Is it empty?
What OS are you using? Are you sure the path of /var/lib/mysql is the right one for your OS?
Are you able to see DB's in phpMyAdmin? Have you tryed repair them?
