Issues with inserting Member Wizard widgets into Wordpress sites

A number of users have reported having problems inserting particularly the Class List into their Wordpress Site. Users report the orange spinner appears and says Loading....but goes no further. Below is a fix for this. 

In order for widgets such as the Class List and Member Portal to operate in Wordpress, a "custom HTML" box needs to be created.

Go to "Edit HTML".

Paste the widget script from MW into the custom HTML box.

Press UPDATE.

On the edit screen, "Loading...Please wait" will appear.

Save the page and view the webpage outside of Wordpress and the Member Wizard widget will appear.
