Text using the List Bullet style has lost all of its formatting

Problem

I've just published the slide show and all of the bullet points (based on List Bullet) are displayed as ordinary text using Times New Roman and with no bullets.

Reason

This can happen if the List Style setting for the Style object has been changed to None or Skip Numbering (if the Style object has been modified, or the template the Style object is based on has been changed). This setting is checked when the presentation is published.

Solution

Open the Style object and choose the HTML > List Style sub tab and choose the Bullet list style.
