How it works
The Welcome Bar plugin works on every page of your site, you don't need to activate on particular pages, you don't need to setup anything inside the plugin settings.
So let's do an example:
You created a Welcome Bar that you'd like to show on a particular page.
The base URL of your site is mycompany.com, so the Welcome Bar will be:
Calling this URL, the Welcome Bar will appear on the home page of your site, but actually the Welcome Bar will work on every page of your site, so for example:
As you can see, doesn't matter which page you use, the Welcome Bar will be called everywhere using the "welcome" tag as in the example above.
