    The database file is larger than the configured maximum database size.

    Hello everyone,

    I have that error,

    Parser Error Message: The database file is larger than the configured maximum database size. This setting takes effect on the first concurrent database connection only. [ Required Max Database Size (in MB; 0 if unknown) = 257 ]

    I really need your help

    Hi Idris,

    If it an SQLCE database you are using take a look at this link:

    Or if you are using a Microsoft SQL database, this link may help you

    You need to locate the connection string and add: Max Database Size = 4096 (4GB), it works. Wait for 10 minutes.

    web.config file

    <add name="umbracoDbDSN" connectionString="Data Source=|DataDirectory|\Umbraco.sdf Max Database Size=4096"

       providerName="System.Data.SqlServerCe.4.0" />

    This doesn't work for me. I changed my connection-String to:

    <add name="umbracoDbDSN" connectionString="Data Source=|DataDirectory|\Umbraco.sdf; Max Database Size=4096;" providerName="System.Data.SqlServerCe.4.0" />

    But i still get an error. I cant access the backend or frontend.
