Some times, we will get the following error when we try to drop the database from PHP my admin.
DROP DATABASE `databasename`
#6 – Error on delete of ‘./databasename’ (Errcode: 13)
The problem is with wrong permission of /var/lib/mysql. You can fix the issue by changing the permission of mysql data directory to mysql .
#chown mysql.mysql /var/lib/mysql.
Now, you are able to drop the database from PHP my admin.
