Vantage Child Theme Broken Grid Layout
I have the same problem as described in another thread. I am using Vantage child theme.
I have the two necessary files in the root folder of the child theme.
I have created a new home page with the necessary Template assigned and put a home content widget with the grid view for Listings. It just shows the main idea of the child theme but with broken layout, instead of a grid as shown in your screenshots.
By the way your demo doesn't show the grid examples as well, just general Vantage arrangement. May be you should have a look on it.
Let me know when you can have a look on my issue. I will prepare a clone of the website, as the website is live and I cannot put a non-working homepage, so you can login and check out what's up.
The idea of the plugin is great, the screenshots as well, so looking forward to hearing from you to make it work on my website.
