I’d suggest reaching out to the Design Studio authors, they’ll probably have a better understanding of what is going on since they wrote the theme.
I recommend asking at https://wordpress.org/support/theme/designstudio#new-post so the theme’s developers and support community can help you with this.
Thank you so much and so fast! I did just what you said. Thank you – new to the forum.
Ok this was resolved for me by a WP meetup buddy and I’m sharing the solution here and in my other post:
#main-content {float:none; margin: auto;}
Thanks again!
