If you want to remove the sidebar, go to wp-admin>theme options>posts settings>single post sidebar And select none as the single post default side bar.
If you want to edit the sidebar content, please go to wp-admin>appearance>widgets, And edit the Default Sidebar widget area
how do I remove all the unwanted text on the right side?
Hi Stuart,
If you want to remove the sidebar, go to wp-admin>theme options>posts settings>single post sidebar
And select none as the single post default side bar.
If you want to edit the sidebar content, please go to wp-admin>appearance>widgets,
And edit the Default Sidebar widget area
Thanks,
