body: Hello Klaus,

Thank you for contacting us. I've seen this error in the past where the database user didn't have proper permissions. I would recommend reading through this post:

* [Atlassian Community: Cannot call sendError after the response has been committed](https://community.atlassian.com/t5/Confluence-questions/Cannot-call-sendError-after-the-response-has-been-committed/qaq-p/933173)

To resolve this, have a look at this article:

* [Database Setup for SQL Server](https://confluence.atlassian.com/doc/database-setup-for-sql-server-9258.html?_ga=2.9788085.1294575221.1558945229-1483961444.1556008674#DatabaseSetupforSQLServer-2.Createadatabaseanddatabaseuser)

Give this user full create, read and write permissions for the database tables. Confluence must be able to create its own schema. Refer to the SQL Server documentation for how to do this.

Can you have a look at that and let me know if it helps?

Regards,

Shannon
