In footer, the 4th column is dropping under the 3rd column

Hey Christy,
Thanks for the link to your site, I see that you are using v4.7.6.4, you may wish to update to v5.1.2.
The issue with your footer columns is that the 1/4 columns have a width of 24.5% where they should have a with of 20.5%
Please check your custom css for this, or try this css in Enfold Theme Options ▸ General Styling ▸ Quick CSS field

#footer .av_one_fourth {
    margin-left: 6%;
    width: 20.5%;
}
#footer .first.av_one_fourth {
    margin-left: 0%;
}

After applying the css, please clear your browser cache and check.

Best regards,
Mike
