1. [Administrative Functions](administration#admin-functions)
Site administration is limited to users with full system permissions. Administration tasks are infrequent and may be carried out by a journal manager, senior editor, or a dedicated site administrator. For more detailed information, see [Learning OJS: Site Administration](https://docs.pkp.sfu.ca/learning-ojs/en/site-administration).
## <a name="hosted-journals"></a>Hosted Journals
Add, edit or remove journals hosted on this installation. There will only be one journal in most cases, but you can host multiple journals with a single installation.
Administrators, journal managers or senior editors can access a **Settings Wizard** for each hosted journal, which will walk you through the basic journal setup steps. These include setting up the masthead, contact details, site appearance, submission parameters, indexing details, and users.
## <a name="admin-functions"></a>Administrative Functions
Several administrative functions are available in the site administration area. These should be used with caution by technical administrators. Improper use could lead to unexpected results.
### System Information
Detailed information about the software version and server configuration. These details are useful for receiving support on the PKP Forums.
### Expire User Sessions
This link will log all users out of the system immediately. This can be useful just before conducting a software upgrade.
### Clear Data Caches
Clears all cached data, including locale information, help cache, and search cache.
### Clear Template Cache
Clears all cached versions of HTML templates. This function may be useful to force templates to be reloaded after customizations have been made.
### Clear Scheduled Task Execution Logs
Remove log files generated automatically by some scheduled maintenance tasks, such as the processing of statistics.
