Once we upgrade from cPanel 11.24 to 11.25 version. We are receiving lots bug. One of them is database size showing zero in cPanel. To resolve this issue you have to edit following file /var/cpanel/cpanel.config
root@support[~]vi /var/cpanel/cpanel.config
Search line “disk_usage_include_sqldbs” in file “ /var/cpanel/cpanel.config “ and change it
From
disk_usage_include_sqldbs=0
to

And run script
