Hello Kristin,
It’s likely the same issue. JustHost is part of Endurance International, the company that owns BlueHost, Host Gator and others.
It looks like there have been two updates since the version that you’re running. Let’s check this. Go to the Appearance section in your WordPress dashboard and click on Theme Options. In the General tab make sure the option to disable theme updates isn’t checked. If it is, uncheck it and update your settings. Then go to the updates section in your WordPress dashboard and refresh the page. See if the update doesn’t appear.
If it doesn’t, you can still update the old fashioned way. Go to our downloads page here in our support site and download the theme. Unzip the foundation.zip file that you’ve downloaded. Now use a FTP program to upload the theme folder to the wp-content/themes/ folder on your server. You can replace the existing foundation theme with the new one that way. Once upon a time that was the only way to install a WordPress theme, plugin or update.
Let me know if that still doesn’t take care of things for you.
Thanks,
Bill
