I've run a site collection backup using Backup-SPSite. I then deleted the Site Collection using CA. Then tried to restore is using Restore-SPSite. Got the error "No content databases are available for this operation but the site collection is scheduled for deletion in at least one content database. Either wait for the deletion operation to complete or create a content database, and then try the operation again. To create a content database, click "Content databases" on the Application Management page, select the Web application to use, and then click "Add a content database".
I then ran the Gradual Delete Timer Job manually but I'm still getting the error.
Any suggestions? As usual, thanks a million in advance!
