Working with configuration providers
Sitefinity uses one configuration data provider - XmlConfigProvider.
XmlConfigProvider uses standard .config files to store configuration information. Sitefinity allows you to store the .config files either in file system or database.
The default storage location is the file system. To change the location, add the following lines in web.config:
<telerik>
<sitefinity>
<sitefinityConfig storageMode="Database" />
</sitefinity>
</telerik>
All configurations in Sitefinity do not require explicit setting. If a configuration is not set explicitly the default value is used.
NOTE: In Sitefinity backend, you cannot modify configurations from web.config.
