Hello. When I edit thru (appearance-customize), either regular customizing or using powerpack [using powerpack I see the changes take place in the right page image in customizing page], when I click ‘save & publish’ it never saves the changes. I deactivate the WC Vendors plugin and it saves changes OK. Let me know if you would like a temporary user(admin) account to see for yourself. Attached 6 images of all system status. PLS. ASAP
