Hi danielbravo,
You should have a Events option in the left hand menu of your WordPress admin dashboard. Under that is a link to Events which will give you a list of all your events. You can then click into them and edit them. I highly recommend that you check out our New User Primer to see an example of this.
If you’re not seeing that option in your menu, there may be a theme or plugin conflict hiding it. You’ll want to deactivate your other plugins and switch to a default theme like Twenty Thirteen to rule out a conflict. If you can isolate this as an issue that’s inherent to The Events Calendar, we’d be happy to look into it further. Unfortunately, we can’t help troubleshoot conflicts here on the free forum. If you do find a conflict, you can try getting in touch with the developer of the theme or plugin and see if they can shed some light on the issue.
Best,
Leah
