Quick Setup Guides
Single Site Setup
- Install the WhereUsed plugin per instructions above and then activate it.
- Modify settings as need to ensure your entire site gets scanned properly. Adjust settings here: Admin > Tools > WhereUsed > Settings
- Do an initial full scan on the bottom right of the Dashboard here: Admin > Tools > WhereUsed
- Once the scan is complete, you can review the Dashboard to discover detected broken links and redirects.
- Install the WhereUsed plugin per the instructions above and activate the plugin for the entire network or go to each site individually in the network and activate the plugin.
- All sites will default to using the network settings (for convenience). This can be disabled on a per site basis in the network settings area. WP Admin > Network Settings > Settings > WhereUsed
- Each site will need to be scanned so that all references are detected
- Multiple scans (full scan on each site) are prevented from running simultaneously to protect the server from getting too overwhelmed at one time.
- Once all scans have been run, you will be able to see all references on each site and all references between each site.
Navigate to the Plugin management area:
- Single Site: WP Admin > Plugins
- Multisite: WP Admin > Network Admin > Plugins
Click “Add New” button at the top of the Plugins page. A new page will load displaying an Upload button at the top and an area to search for plugins.
