Several administrative functions are available in the site administration area. These functions should generally be used with caution, as improper use could lead to unexpected results.

System Information. General information about the server environment and OJS version history (including past upgrades). A web-based interface to modify the OJS configuration file is also provided.

Expire User Sessions. Clears all active user sessions in the system, requiring any user that is currently logged in to sign in to the system again.

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.
