You have markup errors on your site causing this layout issue.
First, you have a link or anchor tag (<a>
) added on the Custom Head Codes option. That option is only intended for custom <script>
, <meta>
and stylesheet <link>
tags. You could just add your google page link on Frontier Options -> Display -> Footer Text
or on a Text Widget
.
Second, check the content of your 3rd widget on the right sidebar. The <img>
tag is not properly closed. This might be the main cause for the footer issue.
