Snippet Library
Multisite snippets for WordPress
Snippets for WordPress Multisite networks: network-wide settings, new site defaults, super admin tools and cross-site tweaks. For network administrators who manage many sites from one install.
Hide Import and Export From Site Admins
Removes Tools > Import and Tools > Export from subsite dashboards for non-super-admins and blocks the screens, keeping content moves in the network team's hands.
Hide Permalink Settings From Site Admins
Removes Settings > Permalinks from subsite dashboards for non-super-admins so URL structures stay consistent across the network.
Hide the Plugins Screen From Site Admins
Removes the Plugins menu from subsite dashboards for everyone except super admins and blocks direct visits, even if "Enable administration menus" is on in Network Settings.
Let Site Admins Edit Their Own Site's Users
Allows site administrators to edit the profiles of users who belong to their site, which multisite normally reserves for super admins.
Lock the Admin Email on Subsites
Makes the Administration Email Address field on each site's General Settings read-only for site admins, so network notices keep reaching the right person.
Show Network-Active Plugins on Subsite Plugin Screens
Lists network-activated and must-use plugins on each site's Plugins screen for site admins, so they can see what is running without asking.
Stop Site Admins From Deleting Their Own Site
Removes Tools > Delete Site from subsite dashboards and blocks the screen, so only super admins can delete sites from Network Admin.
