Click this button to rebuild Jomres' registry.
You would do this if you've copied a file to a directory in "remote_plugins" or created a new file that you want Jomres to be able to use. This feature helps you to rebuild the jomres registry after you have uploaded/deleted by FTP a new minicomponent in /jomres/remote_plugins.
The registry is updated automatically if you install/uninstall a plugin using the Jomres plugin installer.
Rebuilding registry also helps if you move your site from one place to another (for example from your computer to the online hosting account).
