The Database operation error issue is one of the most common problems detected after a WebEdition installation. It is a general error which is basically saying that connection to the database server (default, SQL Server) could not be established.
There are various reasons why this issue occurs, but most common are:
SQL Server was not installed with 'Mixed mode authentication' option
Web Edition default installation uses 'Mixed mode authentication' to establish connection to SQL Server database. You could double-check this point using MS SQL Server Management Studio, which is a freetool coming with SQL Server Express Edition installer (see below).
NOTETo establish a SQL Server connection using 'Windows authentication' please check this article: FAQ - Ways to access SQL Server in WebEdition

Log file will be created by default at following location: 'C:\TBS\BASvcHost.log'.
