When a database user loses his access to configured databases, you may need to restore that user’s grants to the database using the restoregrants utility on WHM.

The first step you need to make is to access your command line and then use restore grants to restore the user’s database access:

/usr/local/cpanel/bin/restoregrants –cpuser=$cpuser –db={mysql, pg} –dbuser=$dbuser

/usr/local/cpanel/bin/restoregrants –cpuser=$cpuser –db={mysql, pg} –all

Where:

• $cpuser – is the cPanel username that has lost access to databases.
• {mysql, pg} –  is the type of database: mysql for MySQL or pg for PostgreSQL.
• $dbuser – is a database user whose privileges you wish to restore. If you use –dbuser, the $dbuser variable will consist of the database user’s name. If you use –all, the script will restore grants for all of the database users that belong to the cPanel account.
