Admin Tools


Plugin for Omeka Classic. Reunites several minor plugins and code snippets to give site administrators extra tools:

  • Site Under Maintenance: blocks out from Public interface not-logged in users (and also from Admin interface some logged-in users), displaying instead an "Under Maintenance" sign (note: if wanting to customize sign, one can edit the style section in views/shared/maintenance/maintenance.php file).
  • User Manual: allows for a User Manual (or other document) to be made available for logged-in users.
  • Cookie Bar: adds to Public interface a header or footer bar with simple information about cookies and privacy policy via the jQuery cookiebar widget.
  • Limit Visibility to Own: limits Item/Collection/Exhibit visibility to only the ones created by the user (Admin interface).
  • Public Edit Link: adds a edit link to Items/Collections/Exhibits/Files/Simple Pages to Public interface for logged-in users.
  • Database Backup: creates a backup copy of the Omeka database, storing it locally (in Omeka's files directory) and also making it available for download.
  • Sessions Table: allows trimming of the Omeka table recording sessions, in case automatic trimming was not effectively working.
  • Tags Table: allows deleting all unused tags (i.e. tags not associated with any record).

When installed, the plugin creates an Admin Tools page accessible to Super User from the admin navigation sidebar; through the page one can put the website in maintenance mode, clear the languages cache and create a backup copy of Omeka's database. The plugin's configuration page lets fine tune this functions, plus many other ones.


Uncompress files and rename plugin folder "AdminTools".

Then install it like any other Omeka plugin.


Use it at your own risk.

It’s always recommended to backup your files and your databases and to check your archives regularly so you can roll back if needed.
