Hi @csaksham,
I’m sorry that you are having this issue. But it’s happening with a conflict of your WordPress theme.
But I looked into your matter personally and giving you a quick fix. Please add the following lines of CSS into the Custom CSS option in the IgniteUp options page.
html{height:100% !important;}
body{background: BGCOLOR !important; color: FCOLOR !important;}
Please replace text BGCOLOR with your needed background color hex (Some color like #F1F1F1 ). Replace FCOLOR with a hex color code for fonts.
Let me know if it fixed your problem.
Thanks!
