Hi, I have installed the plugin, set up a location, service and worker, created a connection and some timeslots, then embedded the Easy Appointments in a page using the [ea_bootstrap] shortcake. When I publish the page, I get the following message:

East Appointments - Settings validation: You need to define at least one location. You need to define at least one service. You need to define at least one worker. There should be at least one Connection.

Is there something obvious I am missing? I have used this plugin before on a different website and it worked perfectly, so confused what is going wrong here when I have set all the things it is asking for in the error message. Any help gratefully received!
