Hi @woodyevents :
For some reason the Customizer doesn’t appear all section as our documentation. So please do the following steps :
1. If you installed the Jetpack plugin, please go to Jetpack => Settings then deactivate two modules : Extra Sidebar Widgets & Widget Visibility
2. Please try to disable all your plugins ( except OnePress Plus plugin if have ).
3. Update both latest OnePress theme & OnePress Plus version.
4. If none of the above works then send us an email here : https://www.famethemes.com/contact/
Cheers.
