By default, MainWP Dashboard is designed to check for possibly abandoned plugins and themes once per day. But if you want to trigger this process manually:
- Go to the MainWP > Sites > Manage page
- Select Sites that you want to check
- Select the Check Abandoned Plugins or Check Abandoned Themes action in the Bulk Actions menu
- Click the Apply button.
The same process can be manually triggered from the MainWP > Updates page.
For Plugins, go to the MainWP > Updates > Abandoned Plugins and click the Check for Abandoned Plugins button.
For Themes, go to the MainWP > Updates > Abandoned Themes and click the Check for Abandoned Themes button.
