Bullet points in posts not working

Don't know if this is "thread-worthy" or whatever, but when I try to create a bulleted list in a post, the bullet points do not appear.

Let me qualify that: When I'm making the post, I see them, but after I actually post the post, they have disappeared - whatever I attempted to bullet is indented, but without the actual bullet-points.

Is this just me?

Apologies if this has been identified or covered previously.

Cheers!
