[plugins content timeline]

My site is vicccccw.com
Currently, I am using the Themify Ultra theme. I have to say I really like the style of themify themes.

It’s very strange that when I add the shortcode of the content timeline on the TEXT module box in the ultra theme, everything is fine in the front builder, AND when I update the page, no matter what device you use, or browser you use, you can see the content timeline plugin works well. BUT, when you refresh the browser, or use another device or browser to open the site, the content of plugin is missing. In my case, I just use this plugin to present my career and study history. I can see it well in the front builder and at the very first time in the browser after updating.

I have done some simple troubleshooting, such as use a themify basic theme and add the same shortcode, everything works fine. So I just guess the problem comes from the theme, which is the themify Ultra.

I do appreciate any help from you guys.
