This plugin lets you enter a shortcode tag so that you can check to see if the shortcode is in use in a page or post on your site, and will display a list of pages or posts where the shortcode is in use.
Often times WordPress users will install a plugin to display some feature on their site. Usually these plugins will come with a [shortcode] to make displaying the content a little easier. Sometimes the plugin and shortcode works fine, but after a while you may find another plugin that works better, or simply decide that you don’t want the feature any more.
If you were to deactivate the original plugin without removing its shortcodes from your site’s pages or posts, you will end up with a lot of shortcode tags left over, which do nothing except for look funny on your site.
Figuring out which pages or posts have these shortcodes can be very time consuming.
With this plugin, you simply enter a shortcode tag and it will return a list of every page or post where that particular shortcode tag is being used. You can quickly jump to the edit page for those pages or posts to remove or edit the shortcode if you need to.
If you can’t remember all the shortcodes you want to check, try the Edit Screen Shortcode Lister plugin (https://wordpress.org/plugins/shortcode-lister/) which will list out the shortcodes you have available to use on your site in the page or post edit screen.
