cPanel shows wrong quota for database.

Getting 0.00MB disk quota for databases in cpanel ?

Here is the answer ::

The disk quota for MySQL databases will show 0.00 in cPanel > MySQL Databases area unless this option is selected in WHM's Tweak Settings area:
------------------------
When displaying disk usage in cPanel/WHM include Postgresql and MySQL® disk usage. [Requires MySQL® 5+] (SQL disk usage is only updated every four hours)
------------------------

So go ahead and enable this in Tweak Settings, then manually run the command to update the quotas:

/scripts/update_db_cache

This command will run by cron every 4 hours now that the Tweak Settings option has been enabled.

Thanks
