Good evening Kimberly,
Thank you for your question.
I am sorry to hear you are experiencing difficulties with the events list widget. I would like to try to help you get to the bottom of things.
This might require a bit of back and forth between the two of us, so I would like to thank you in advance for your patience.
The first step is to test for conflicts with other plugins or with your WordPress theme.
Could you tell me if the issue is still there with a basic WordPress theme such as twenty-fifteen or when all other plugins are deactivated ?
Please let me know what the results of these tests are so that we can establish what is causing this situation.
Have a great day!
Geoff B.
