I have noticed that my postgrid is not displaying properly, depending on the browser used. When I look at it on Google Chrome, it looks perfect. But when I look at it on Firefox and others, the posts bunch up together. I was not able to attach the screenshot so I am sharing the URL: https://themillennialsmantra.com/
Welcome to our forum.
If you are using masonry-style grid please clear browser cache or try to deactivate cache plugin and refresh the page to see the result. Let me know the result.
