You can put this to fit first widget not appearing out of position.

If you have access to it change code to:

<iframe id="HookitPlugins_SpotWidget1" onload="HookitPlugins.SpotWidgetLoaded(this)" src="https://www.hookit.com/plugins/spots/?spot_id=port-angeles-bmx&width=300&height=350&borderColor=%23000&borderWidth=1&" style="width: 275px; height: 350px; border: 1px solid rgb(0, 0, 0);"></iframe>

width: 275px

Np. Nice site.

Also you can remove this

.jetpack-image-container:after {
clear: both;
}

or change it to

.jetpack-image-container:after {
clear: none;
}

Sorry. Located here:

wp-content/plugins/jetpack/modules/widgets/widgets.css

change this

.jetpack-image-container:before, .jetpack-image-container:after {
display: table;
content: "";
}

to this

.jetpack-image-container:before, .jetpack-image-container:after {
display: inline-block;
content: "";
}

#advanced_iframe {
height: 7400px /*6994px*/;
overflow: hidden;
position: relative;
left: -25px;
top: -65px /*-340px*/;
}

.content {
height: 7500px;
}

This will show footer.
Anyway, this is not best way of iframing.
You had more simple way of creating your header and adding iframe in simple php page.
Also that could be done with javascript, which would auto resize height of an iframe.

First, I think you shud know about child themes.

When you have child theme, you wont broke your parent theme, and it is more safe.

If you still just want to change style.css in main/parent theme, it is in wp-content/themes/yourtheme/style.css

PS: I tried editing your css throught browser, but didn’t found any better solution than changing height.

In style.css

#advanced_iframe {
height: 6994px;
overflow: hidden;
position: relative;
left: -25px;
top: -340px;
}

You can put height to higher value.

If you uploaded your files directly to host, and not throught wordpress, wordpress won’t change your urls that were pointing to old host.
<a href="olddomain.com/myfile.zip">download</a>
and now your downloads are on:
<a href="newdomain.com/myfile.zip">download</a>
I am just guessing, but maybe problem is in this.

You will need javascript for auto iframe resizing.

I did not realized your question well.
If you changed domain, in wp_options table, did you changed the url of website?

Try settings – permalinks – save
