Good evening Andi and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the display changing after the last update.
I would love to help you with this topic.
Before we begin, I am noticing that there is some CSS missing from your events list widget.
A fix is underway and we will let you know as soon as it’s out.
In the meantime, please add the following CSS rule to your style.css file or Custom CSS section in your theme:
.tribe-mini-calendar-event .list-date .list-dayname {
box-sizing: border-box;
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
}
As for the second issue, I went to http://www.clarkcountytoday.com/events/, but everything seemed OK on my end. Are you using a different URL ?
The smaller calendar normally fires up when the resolution of the screen is 768px or less (like a portrait iPad). You can control that breakpoint as described here: https://theeventscalendar.com/knowledgebase/themers-guide/#responsive
Finally, you can also experiment with the Events Template setting at Events -> Settings -> Display to see if that helps.
Let me know how that goes.
Best regards,
Geoff B.
