Thanks for your response, Jeremy. I will take your advice and refrain from 2:00 am site experimentation:).
I’ll check into the items you mentioned above. The weird thing is that I have done two sites with the same theme and the same events calendar plugin, and both showed up with a sidebar. I don’t think I did anything to put them there. I am so new to this, though, that I am having a difficult time keeping track of what I have done, since I am learning as go along.
To answer your question, I am using Divi Theme for my site.
Off to try a few of your suggestions!
Thanks again,
Amanda
