WPBakery Visual Composer can’t load if permanent link changed

Hi,
The plugin VWPBakeryisual composer (newest version) will not load front end editor if i change permanlinks to anything but day & name. I want my site has only post-name in a link, but if I chose this option, the plugin front end wouldn’t work.

Extra: I’m using Onfleek Themes.

Can anybody figure out what’s happening here?
