Cause

Reseller is lacking resources.

Resellers have their own resources they can sell, and for this particular reseller overselling is not allowed, therefore it is not possible to increase disk limit for his subscription.

Resolution

1. In Plesk go to Resellers > John Doe and click Customize.

   

2. Apply one of the following solutions:

   • Increase disk space limit.

   • Increase amount of allowed MySQL databases.

   • Allow overselling.
