Hello Positive Purchasing,
thanks for the response, the connection is established and the membership "db_owner" is also set.
Hello Chetan Sharma,
plz have a look again.
For clearification:
Our workfow was like:
1. creating a full DB backup
1. restored the database from the full backup on our new server
So far content editing is no problem (create, delete pages - update, change content eg.) so connection could not be the problem.
any futher suggestion
kind regards
stefan
