Ads not showing up in Yoko sidebar

Hi, I just switched from the Genesis child theme Foodie to Yoko. The problem I’m having is that ad content is no longer showing up in the sidebar. I usually use the Text widget for affiliate ads and it’s worked fine in other themes.

The only change I’ve made is that I found some CSS online to convert the double sidebar to a single sidebar. Could that be causing the ads to not display? I seem to remember the ads not showing up even before I edited the CSS. I just switched to Yoko yesterday.

Here’s the code I added (found in a closed thread online):

#content, #content .entry-content {
width: 100%;
}

#main {
width: 72.595%;
}

#tertiary img {
max-width: 100%;
height: auto;
}

@media screen and (max-width: 1024px) {
#tertiary {
width: 23.775%;
}
}

@media screen and (max-width: 880px) {
#main {
width: 100%;
float: none;
overflow: hidden;
}

#tertiary {
width: 100%;
margin-top: 40px;
padding-top: 30px;
border-top: 1px solid #ddd;
}
}

#secondary {
display: none;
}

I used to be able to use the Text widget for displaying ads. Any suggestions? My understanding of CSS is minimal, but I’m comfortable copying and pasting code and using widgets. THANKS!
