Hi,
During Monitoring Reports deployment, I've unintentionally granted ReadOnly permission to user administrator. Now I access to https://servername/reports and only view directories. I don't have any buttons, such as "new folder" or "new data source". I tried to rerun Monitoring Reports deployment - no result. In SQL management console for administrator user I unchecked ReportsReadOnlyRole for databases where this role exists. And also granted administrator user dbowner for all databases - no result.
