Settings and CSS not showing after updating theme

Hey there brilliant WPMU folks!

I recently updated the theme on this website, hartfamilychiro.com, and the styles and settings are not appearing. In the past when I have updated the theme it sometimes takes a couple of hours for all of the settings to show but this has been about a week.

Would you mind having a look and telling me if there is something I am missing. I have granted support access so you should be able to have a look for yourselves and tell me what you think.

If you go under Qode options>header you will see that the header is set to a dark color though it is showing up as white. Also, the CSS that I have within the pages and within the Qode option>general settings is not showing up either.

I have had this problem before. A friend said that it might have something to do with the PHP? I think that y'all have helped me with the issue before though in searching my questions that I asked I do not see an answer. Thank you for your help.

Pura Vida,
Mandy
