Hey Jill,
Sorry you’re having trouble here. I went to the link you provided, but was prompted to provide some login information.
I then tried to submit of my own from the Community submission form, so that I could look at that page without logging in because we cannot log in to customer sites – however, the Anti-Spam features said “Internal server error”, and therefore I was not able to submit an event.
Would you be willing to temporarily disable the anti-spam features so we can try creating a front-end submitted event, and view the “list” page without logging in?
Alternatively, you can test some things on your own: if the buttons are overlapping, it’s likely a CSS-related issue, which means your current theme is the source of that problem. If you’re able to, you can test if this is the case by activating a default theme like Twenty Twelve (or any more recent variant of the default themes, too). See how the buttons look in this theme – if they are not overlapped, but then are again when you re-activate your custom theme, we can confirm your custom theme is the source of the problem. You could then contact your custom theme’s developer for help correcting the CSS there.
Thanks!
George
