Most of the times errors are caused by a plugins conflicting with each other, the theme, or the WordPress core. Deactivating all WordPress plugins on your site will most likely solve the problem. You can then find out which plugin was causing the issue by activating plugins one by one on your site.

The issue can also be caused by a customization made in your child theme. To check, simply activate the Jupiter X parent theme in Appearance > Themes.
Switch to a Default WordPress Theme
You can check whether it’s the Jupiter X theme causing the issue on your website or not by switching to the default theme.
From the WordPress left menu, go to Appearance > Themes page and then click on the Activate button next to a default theme (Twenty Seventeen, for example).
