0.00MB Mysql DB size

On your Cpanel > MySQL Databases > Current Databases size shows as 0.00 MB

To correct this please do the following process
1. vi /var/cpanel/cpanel.config
disk_usage_include_sqldbs value should be "0" change to "1" and wq from your vi editor
ie, it should be as disk_usage_include_sqldbs=1

2. # /scripts/update_db_cache

3. Login to WHM >> Main >> Server Configuration >> Tweak Settings
put "tick" mark for "Calculate the disk usage of account MySQL and PostgreSQL databases" under SQL section
By default it is tick marked in WHM

This will fix your issues. :)
