Mysql Database size showing '0' in cPanel

In cPanel >> mysql databases , it shows database size as 0 even if it is not.

Make the following changes to fix.

nano var/cpanel/cpanel.config 

and search for following line.

disk_usage_include_sqldbs=0 ( set it to 1 instead of 0 )

then run following command

/scripts/update_db_cache

You are done.
